7-38 somebody has built the circuit in fig. 7-35, except for changing the voltage divider as follows: r1 5 150 kv and r2 5 33 kv. the builder cannot understand why the base voltage is only 0.8 v instead of 2.16 v (the ideal output of the voltage divider). can you explain what is happening?

Answers

Answer 1

The base voltage of 0.8 V instead of the expected 2.16 V in the circuit of Fig. 7-35 with R1 = 150 kΩ and R2 = 33 kΩ is likely due to the loading effect caused by the input impedance of the transistor.

The input impedance of a transistor is not infinite and acts as a load on the voltage divider formed by R1 and R2. This loading effect reduces the output voltage of the voltage divider, which in turn reduces the base voltage of the transistor.

In the circuit of Fig. 7-35, the base voltage is given by Vb = Vcc × R2 / (R1 + R2). With R1 = 150 kΩ, R2 = 33 kΩ, and Vcc = 5 V, the expected base voltage is 2.16 V. However, due to the loading effect, the actual base voltage is reduced to 0.8 V. To minimize this effect, a transistor with a higher input impedance or a buffer circuit can be used.

Answers

The type of member function that may be called from a statement outside the class is a public function. Public functions are accessible from outside the class and can be called by any part of the program.

This is in contrast to private functions, which are only accessible from within the class and cannot be called from outside the class. In addition, there is another term that is related to public and private functions, which is "global".

Global functions are functions that are not part of a class and can be accessed from anywhere in the program. They are similar to public functions in that they are accessible from outside the class, but they are not part of any specific class.

It is important to use public and private functions to control the access to the members of a class. Public functions are used to provide an interface to the class that can be accessed from outside the class, while private functions are used to encapsulate the implementation details of the class and are not accessible from outside the class.

This manipulator is used to establish a field width for the value that follows it: field_width set field setw iomanip None of these

Answers

The manipulator used to establish a field width for the value that follows it is setw from the iomanip library in C++. It allows you to specify the number of characters that should be used for the output of the value.

For example, if you want to output a value with a field width of 5, you would use set w(5). This will ensure that the value is formatted with 5 characters, adding spaces as necessary to achieve the desired width. So the correct option in this case would be "set field setw iomanip". The term "set field set w iomanip" does not make sense in this context.
The manipulator used to establish a field width for the value that follows it is "setw". This term is part of the iomanip library in C++. So, the correct answer is "setw".

The manipulator in question is called "setw" and it is a part of the "iomanip" library in C++. option c is correct.

This manipulator is used to set the field width for the value that follows it. The value can be a string, integer, or any other data type.

The purpose of setw is to make the output more readable and organized by aligning the data in columns. For example, if you are printing a table with multiple columns, you can use setw to set the width of each column so that the data is aligned and easy to read.

The syntax for using setw is as follows:

cout << setw(10) << "Hello";

In this example, setw(10) sets the field width to 10 characters for the string "Hello". This means that "Hello" will be printed with a width of 10 characters, even if it is shorter than that. If the string is longer than 10 characters, it will be truncated to fit within the allotted space.

Overall, setw is a useful manipulator for formatting output in C++. It helps to make the output more readable and organized, which is important when dealing with large amounts of data.

fermentation tank in a pullman brewpub is rated for a maximum absolute pressure of 75 psia. a bourdon gauge attached to the tank reads 64 psig. is there a danger that the pressure limit for the fermentation tank has been exceeded? explain why or why not

Answers

Yes, there is a danger that the pressure limit for the fermentation tank has been exceeded. This is dangerous because the tank could rupture or explode if the pressure continues to increase.

This is because:

First, it's important to understand what "absolute pressure" and "psig" mean in this context. Absolute pressure is the total pressure exerted by a gas, including atmospheric pressure (which is around 14.7 psi at sea level). Psig, on the other hand, refers to the pressure exerted by a gas above atmospheric pressure. So if a tank has a reading of 64 psig, that means the gas inside is exerting a pressure of 64 psi above atmospheric pressure.

Now, let's look at the numbers. The fermentation tank in the Pullman brewpub is rated for a maximum absolute pressure of 75 psia. This means that the total pressure inside the tank (including atmospheric pressure) should not exceed 75 psi. However, the bourdon gauge attached to the tank reads 64 psig, which means that the pressure inside the tank is actually 78.7 psia (64 psig + 14.7 psi atmospheric pressure).

This is above the maximum absolute pressure rating of 75 psia for the tank, which means that the pressure limit for the fermentation tank has been exceeded. This is dangerous because the tank could rupture or explode if the pressure continues to increase. It's important to take immediate action to relieve the pressure and prevent further build-up to ensure the safety of the people working with the tank and the surrounding area.

#SPJ11

Hi! Your question is whether there is a danger that the pressure limit for the fermentation tank in a Pullman brewpub has been exceeded, given that it is rated for a maximum absolute pressure of 75 psia, and the Bourdon gauge reads 64 psig.

To answer this, we need to compare the actual absolute pressure in the tank to the rated maximum absolute pressure limit.

Step 1: Convert the gauge pressure (psig) to absolute pressure (psia).
Gauge pressure measures pressure relative to atmospheric pressure. To convert it to absolute pressure, add the atmospheric pressure to the gauge pressure. The standard atmospheric pressure is approximately 14.7 psi.

Absolute Pressure = Gauge Pressure + Atmospheric Pressure
Absolute Pressure = 64 psig + 14.7 psi (approximately)

Step 2: Calculate the absolute pressure.
Absolute Pressure = 64 + 14.7
Absolute Pressure ≈ 78.7 psia

Step 3: Compare the calculated absolute pressure to the maximum pressure limit.
In this case, the calculated absolute pressure (78.7 psia) is higher than the maximum rated pressure limit of the fermentation tank (75 psia).

In conclusion, there is a danger that the pressure limit for the fermentation tank has been exceeded, as the calculated absolute pressure (78.7 psia) is higher than the rated maximum absolute pressure limit (75 psia).

Answers

Unfortunately, I cannot provide a recommended convection coefficient for this case as the information provided is insufficient to calculate it. However, it is stated that to operate at a larger current of 8.1 A while maintaining the rod temperature within the safety limit, the convection coefficient would have to be increased by increasing the velocity of the circulating air.

This means that increasing the velocity of the air would help in dissipating the heat generated by the larger current and prevent the rod from overheating.It is not possible to provide a specific recommended convection coefficient for this case without additional information about the specific application and operating conditions. The convection coefficient is dependent on a variety of factors, including the geometry of the system, the velocity of the air, and the temperature difference between the rod and the surrounding air.However, in general, increasing the velocity of the circulating air can help to increase the convection coefficient and improve heat transfer from the rod to the surrounding environment. This can help to maintain the rod temperature within a safe operating range while allowing for a larger current of 8.1 A.In practical applications, the recommended convection coefficient may be specified by industry standards or guidelines, or may be determined through experimentation or simulation. It is important to ensure that the convection coefficient is properly calculated and applied to ensure safe and reliable operation of the system.To determine the recommended convection coefficient for operating at a larger current of 8.1 A while maintaining the rod temperature within the safety limit, we need more information about the specific system, materials, and safety limits.

if reynolds experiment was performed with a 38-mm- id pipe, what flow velocity would occur at transition?

Answers

Note that the flow velocity at transition for a 38-mm-ID pipe carrying water at 20°C is approximately 0.615 m/s.

What is the explanation for the above response?

Reynolds experiment is used to determine the transition point from laminar to turbulent flow in a pipe, and it depends on the Reynolds number (Re) which is defined as the ratio of inertial forces to viscous forces. The Reynolds number can be expressed as:

Re = ρVD/μ

where:

ρ = density of the fluid

V = velocity of the fluid

D = diameter of the pipe

μ = viscosity of the fluid

For transition to occur in a pipe, the critical Reynolds number (Rec) is approximately 2300. If the Reynolds number is less than Rec, the flow is laminar, and if it is greater than Rec, the flow is turbulent.

To determine the flow velocity at transition for a 38-mm-ID pipe, we need to know the properties of the fluid flowing in the pipe. Let's assume that the fluid is water at a temperature of 20°C, which has a density of 998.2 kg/m³ and a viscosity of 1.002 x 10^-3 Pa.s.

The diameter of the pipe is 38 mm, which is equivalent to 0.038 m. Therefore, the Reynolds number can be calculated as:

Re = (ρVD)/μ = (998.2 kg/m³ x V x 0.038 m)/(1.002 x 10^-3 Pa.s)

For transition to occur, the Reynolds number should be equal to Rec, which is 2300. Therefore, we can rearrange the equation to solve for V:

V = (Reμ)/(ρD) = (2300 x 1.002 x 10^-3 Pa.s)/(998.2 kg/m³ x 0.038 m)

V = 0.615 m/s

Therefore, the flow velocity at transition for a 38-mm-ID pipe carrying water at 20°C is approximately 0.615 m/s.

The flow velocity at transition in a Reynolds experiment with a 38-mm-ID pipe would depend on the Reynolds number. Reynolds number is the ratio of inertial forces to viscous forces and is used to predict the onset of turbulence in fluid flow.

In general, transition to turbulence occurs at a Reynolds number between 2,000 and 4,000 for pipe flow. However, the specific value at which transition occurs depends on factors such as surface roughness and fluid properties.

Therefore, without knowing the fluid and surface properties, it is impossible to accurately determine the flow velocity at transition in a Reynolds experiment with a 38-mm-ID pipe.
Hi! To determine the flow velocity at the transition point in a 38-mm-ID pipe, we need to use the Reynolds number (Re) formula:

Re = (ρ * v * D) / μ

where:
- Re is the Reynolds number
- ρ is the fluid density (in kg/m³)
- v is the flow velocity (in m/s)
- D is the pipe diameter (in m)
- μ is the dynamic viscosity of the fluid (in Pa·s)

At the transition point, the Reynolds number is typically around 2,000 to 4,000. Let's assume a value of 2,300 for this calculation. To find the flow velocity (v), we'll need to rearrange the formula:

v = (Re * μ) / (ρ * D)

However, we don't have values for the fluid density (ρ) and dynamic viscosity (μ). These values will depend on the specific fluid being used in the experiment.

Once you have the values for ρ and μ, plug them into the formula along with the pipe diameter (D = 0.038 m) and the assumed Reynolds number (Re = 2,300) to find the flow velocity (v) at the transition point.

Answers

In a concentric tube heat exchange with an area of 100 m2, 5 kg/s of water enters at 50°C and is heated by oil with a specific heat of 2.1 kJ/kg and a flow rate of 8 kg/s. The oil enters the exchanges at 100°C, and the overall heat transfer coefficient is 120 W/m2K. Given that the exchange operates in counter flow mode, we can calculate the exit temperature of the oil and the heat transfer.

First, let's determine the heat transfer rate (Q) using the formula Q = m_water * c_water * (T_out_water - T_in_water), where m_water is the mass flow rate of water, c_water is the specific heat of water (4.18 kJ/kgK), and T_out_water and T_in_water are the outlet and inlet temperatures of water, respectively.
Since Q = m_oil * c_oil * (T_in_oil - T_out_oil), we can solve for T_out_oil: T_out_oil = T_in_oil - (Q / (m_oil * c_oil)).
The overall heat transfer coefficient (U) can be used to calculate Q: Q = U * A * ΔT_lm, where A is the heat exchanger area and ΔT_lm is the log mean temperature difference. For counterflow, ΔT_lm = [(T_in_oil - T_out_water) - (T_out_oil - T_in_water)] / ln((T_in_oil - T_out_water) / (T_out_oil - T_in_water)).
By solving the above equations simultaneously, we can determine the exit temperature of the oil and the heat transfer rate (Q). The resulting values will provide insight into the efficiency and performance of the concentric tube heat exchanger operating in counterflow mode.

A suction line accumulator is used to ensure that liquid refrigerant enters the compressor.True or False

Answers

False. A suction line accumulator is used to ensure that only vapor refrigerant enters the compressor, while any liquid refrigerant is stored in the accumulator until it can evaporate and turn into vapor.
False. A suction line accumulator is used to prevent liquid refrigerant from entering the compressor. Its purpose is to collect and temporarily store any excess liquid refrigerant, allowing only vapor refrigerant to pass through to the compressor.False.

A suction line accumulator is a component used in refrigeration systems to prevent liquid refrigerant from entering the compressor. Its purpose is to collect and store any liquid refrigerant that may be present in the suction line and vaporize it before it reaches the compressor. The accumulator accomplishes this by having a baffle inside the accumulator that separates the liquid refrigerant from the refrigerant vapor. The refrigerant vapor is then allowed to exit the accumulator and continue on to the compressor, while the liquid refrigerant is stored at the bottom of the accumulator until it vaporizes and can also exit.If liquid refrigerant were to enter the compressor, it could cause damage to the compressor due to the compressor being designed to compress vapor refrigerant and not liquid refrigerant. Liquid refrigerant in the compressor could also lead to reduced efficiency and cooling capacity of the refrigeration system.herefore, the correct statement is that a suction line accumulator is used to prevent liquid refrigerant from entering the compressor, not to ensure that it enters the compressor.

During useful life period, the reliability at mean time to failure (MTTF) is 0. 368, during wear out part of the life studied using Weibull model, when would one observe same reliability?

Answers

Assuming a shape parameter of = 2, the dependability at the same MTTF during the wear-out phase would be noticed at a time of roughly 0.211 time units. The time at which the same reliability is seen will, however, differ if the form parameter is altered.

How to explain the information

We can leverage the correlation between the MTTF and the Weibull distribution's scale parameter as follows:

MTTF = η * Γ(1 + 1/β)

where gamma is the function.

We can use the following method to solve for the scale parameter given the MTTF of 0.368:

η = MTTF / Γ(1 + 1/β)

Assuming a shape parameter of = 2 (which translates to a constant failure rate), the following results are obtained:

η = 0.368 / Γ(1 + 1/2) = 0.368 / Γ(3/2) ≈ 0.211

When your hand is a short distance away, a _________ muffler feels hotter. Assume that the mufflers are both at the same temperature
A. shiny
B. rusted
C. both would feel the same
D. impossible to tell from the information provided

Answers

When your hand is a short distance away, a closer muffler feels hotter than one that is farther away. This is because the intensity of heat decreases with distance, and the closer muffler is emitting more heat towards your hand than the one that is farther away.

However, assuming that both mufflers are at the same temperature, it would be impossible to tell which one feels hotter based solely on their distance from your hand. Other factors that can affect how hot a muffler feels include its material and design, as well as environmental factors such as wind and humidity. For example, a muffler made of a poor heat-conducting material may feel cooler than one made of a good heat conductor, even if they are both at the same temperature. Additionally, if there is a strong wind blowing towards the muffler, it may cool down faster and feel cooler to the touch than it would in still air. In summary, while the distance between your hand and a muffler can affect how hot it feels, there are other factors that can also come into play. Without more information about the mufflers and the surrounding environment, it would be impossible to determine which one feels hotter based on their distance from your hand alone.

true or false. all else being equal, eccentricity in loading improves the ability of a line weld to support the load.

Answers

False. All else being equal, eccentricity in loading reduces the ability of a line weld to support the load. Eccentricity refers to the deviation of the applied load from the centerline of the weld, which creates a bending moment that can lead to failure or deformation of the weld. A weld that is loaded concentrically, or along its centerline, is better able to support the load without experiencing these detrimental effects.

False. Eccentricity in loading refers to the application of a load that is not centered on the axis of the weld. In general, eccentric loading is not desirable as it creates bending moments on the weld, which can lead to increased stresses and potential failureThe ability of a line weld to support a load is influenced by various factors, including the quality of the weld, the material properties, and the design of the joint. The load capacity of a weld can be improved by proper design, such as increasing the weld size or using stronger materials.Therefore, it cannot be said that eccentricity in loading improves the ability of a line weld to support the load. In fact, it is generally considered detrimental to the weld's ability to support load. Welds are designed to handle axial loading, and eccentric loading can lead to premature failure of the weld. Hence, it is important to avoid eccentric loading whenever possible and ensure that the weld is properly designed and fabricated to handle the intended loads.
False. Eccentricity in loading refers to the application of a load away from the central axis, which can create additional stresses on a line weld. This may reduce the ability of the line weld to support the load effectively, as it could lead to a higher risk of failure under the uneven distribution of stress.

a lot of research has gone into making small improvements on pressure ratio for a stage in an axial compressor. it took about 25 years to come from a pressure ratio of 1.15 to 1.23 per stage. is it worth the effort? take an axial compressor with total pressure ratio of 24 and explain in terms of number of stages and power to weight ratio of the gas turbine

Answers

The decision of whether it is worth the effort to make small improvements on pressure ratio for a stage in an axial compressor depends on various factors such as the specific application, the cost of the improvements, and the benefits that the improvements may provide.

In the case of a gas turbine with a total pressure ratio of 24, the number of stages required to achieve this pressure ratio would depend on the pressure ratio per stage. If each stage has a pressure ratio of 1.23, then the number of stages required would be:

24 / 1.23 = 19.51

Since the number of stages must be an integer, the gas turbine would require 20 stages to achieve a total pressure ratio of 24.

The power to weight ratio of the gas turbine is an important metric for assessing its efficiency and performance. Improving the pressure ratio per stage can result in a higher total pressure ratio for the gas turbine, which can lead to improved power output and efficiency. However, this improvement comes at the cost of additional weight and complexity in the form of additional compressor stages.

Therefore, the decision to invest in improving the pressure ratio per stage in an axial compressor should be made after considering the potential benefits in terms of improved power output and efficiency, as well as the costs associated with additional weight and complexity.

A parallel circuit has a resistance values of 1,200 ohm, 2,200 ohm, and 3,000 ohm. If the circuit has a total current flow of 0.25 Ampre. How much current flows through each of the resistors

Answers

In a parallel circuit, the voltage across each resistor is the same, while the current through each resistor is different.

To find the current through each resistor, we can use Ohm's Law:

I = V / R

where I is the current, V is the voltage, and R is the resistance.

Since the voltage is the same across each resistor in a parallel circuit, we can use the total current and the resistance values to find the current through each resistor.

Let's start with the first resistor:

I1 = V / R1
I1 = 0.25 / 1200
I1 = 0.00020833 A

Now, let's find the current through the second resistor:

I2 = V / R2
I2 = 0.25 / 2200
I2 = 0.00011364 A

Finally, let's find the current through the third resistor:

I3 = V / R3
I3 = 0.25 / 3000
I3 = 0.00008333 A

Therefore, the current flowing through the first, second, and third resistors are 0.00020833 A, 0.00011364 A, and 0.00008333 A, respectively.

Give me three types of control systems

Answers

There are various types of control systems, but here are three common types:

1. Open-loop control system: In this type of system, the control action is determined solely by the input signal. The output of the system is not compared to the desired output or reference signal. An example of an open-loop control system is a washing machine with a timer that runs for a fixed duration regardless of the state of the clothes inside.

2. Closed-loop or feedback control system: In this type of system, the output of the system is measured and compared to the desired output, and the control action is adjusted accordingly. This type of system uses feedback to continuously adjust the output to match the desired value. An example of a feedback control system is a thermostat that measures the temperature of a room and adjusts the heating or cooling system to maintain a desired temperature.

3. Digital control system: In this type of system, the control variables are processed digitally. The input and output signals are sampled and converted to digital signals, and then the control algorithm is executed using digital processing techniques. This type of system is commonly used in modern industrial control systems and robotics.
Three basic types of control systems are available to executives:
(1) output control,
(2) behavioral control, and
(3) clan control.
