The aliased frequency that is due to small sampling frequency is 675 Hz.

The proposed sampling frequency is 2f = 120

The signal frequency that is given in the question is 60Hz

The sampling frequency is 90Hz

a. Using Nyquist frequency,

fn = 0.5*90Hz = 45Hz

The aliased frequency =  |n*fn - fs|

aliased frequency = |n*fn - fs|

We have  n >= 1/Fs = 17ms

Then the aliased frequency is = 17 x 45 - 90

= 675 Hz

In order to avoid aliasing the sampling frequency, this has to be at least two times the highest frequency.

Therefore Fs =

The Given Data were properly outline and the relation for the quantity of heated at equilibrium was used to compute the temperature as 18.84°C

Given Data

At equilibrium, the final temperature of the system T2 will be same for both copper and water

McΔT(copper) = McΔT(water)

0.3*490*(T2 - 150) = 4*4180*(T2-20)

147*(T2 - 150) =16720*(T2-20)

147T2 - 22050 = 16720T2 - 334400

collect like terms

147T2 -16720T2  = - 334400+22050

147T2 -16720T2  = - 334400+22050

-16573T2 = -312350

16573T2 = 312350

Divide both sides by 16573

Hold the tape in place and go down to the end.

Explanation:

Answer:

ill try to help you :)

Explanation:

By using the boundary layer equation, the average heat transfer coefficient for the plate is equal to 4.87 W/m²k.

Given the following data:

Surface temperature = 15°C

Bulk temperature = 75°C

Side length of plate = 150 mm to m = 0.15 meter.

Since we have a quiescent room air and a uniform pole surface temperature, the film temperature is given by:

[tex]T_f=\frac{T_{s} + T_{\infty} }{2} \\\\T_f=\frac{15 + 75 }{2} \\\\T_f = 45[/tex]

Film temperature = 45°C to K = 273 + 45 = 318 K.

For the coefficient of thermal expansion, we have:

[tex]\beta =\frac{1}{T_f} \\\\\beta =\frac{1}{318}[/tex]

From table A-9, the properties of air at a pressure of 1 atm and temperature of 45°C are:

Next, we would solve for the Rayleigh number to enable us determine the heat transfer coefficient by using the boundary layer equations:

[tex]R_{aL}=\frac{g\beta \Delta T l^3}{v\alpha } \\\\R_{aL}=\frac{9.8 \;\times \;\frac{1}{318} \;\times \;(75-15) \;\times \;0.15^3 }{1.750 \times 10^{-5}\; \times \;2.416 \times 10^{-5} } \\\\R_{aL}=\frac{9.8\; \times 0.00315 \;\times \;60\; \times\; 0.003375 }{4.228 \times 10^{-10} }\\\\R_{aL}=1.48 \times 10^{7}[/tex]

Also take note, g(Pr) is given by this equation:

[tex]g(P_r)=\frac{0.75P_r}{[0.609 \;+\;1.221\sqrt{P_r}\; +\;1.238P_r]^\frac{1}{4} } \\\\g(P_r)=\frac{0.75(0.7241)}{[0.609 \;+\;1.221\sqrt{0.7241}\; +\;1.238(0.7241)]^\frac{1}{4} }\\\\g(P_r)=\frac{0.543075}{[0.609 \;+\;1.221\sqrt{0.7241}\; +\;1.238(0.7241)]^\frac{1}{4} }\\\\g(P_r)=\frac{0.543075}{[2.5444]^\frac{1}{4} }\\\\g(P_r)=\frac{0.543075}{1.2630 }[/tex]

g(Pr) = 0.430

For GrL, we have:

[tex]G_{rL}=\frac{R_{aL}}{P_r} \\\\G_{rL}=\frac{1.48 \times 10^7}{0.7241} \\\\G_{rL}=1.99 \times 10^7[/tex]

Since the Rayleigh number is less than 10⁹, the flow is laminar and the condition is given by:

[tex]N_{uL}=\frac{h_{L}L}{k} = \frac{4}{3} (\frac{G_{rL}}{4} )^\frac{1}{4} g(P_r)\\\\h_{L}=\frac{0.02699}{0.15} \times [\frac{4}{3} \times (\frac{1.99 \times 10^7}{4} )^\frac{1}{4} ]\times 0.430\\\\h_{L}= 0.1799 \times 62.9705 \times 0.430\\\\h_{L}=4.87\;W/m^2k[/tex]

Based on empirical correlation method, the average heat transfer coefficient for the plate is given by this equation:

[tex]N_{uL}=\frac{h_{L}L}{k} =0.68 + \frac{0.670 R_{aL}^\frac{1}{4}}{[1+(\frac{0.492}{P_r})^\frac{9}{16}]^\frac{4}{19} } \\\\h_{L}=\frac{0.02699}{0.15} \times ( 0.68 + \frac{0.670 (1.48 \times 10^7)^\frac{1}{4}}{[1+(\frac{0.492}{0.7241})^\frac{9}{16}]^\frac{4}{19} })\\\\h_{L}=4.87\;W/m^2k[/tex]

Step-by-step Explanation:

The strength is mainly depends on the some of factors which are described below.

●molecular structure:- The molecular structure is responsible fir the intermolecular force of a metal or material which causes the increase and decrease of strngth of a metal. Tungsten molecular structure is much stringer then that of aluminium.

●Temperature:-The temlerature also plays a rule in the strenghtNess of a metal. Tge high temprature makes a metal soft.

●Composition :- The composition is mostly important for the strengthnesa of material. For ex the pure iron metal is much weeker the alotrophy of iron.

Due to the fact that there is a 14.3inch deflection in the manometer, water is flowing towards the regions that have low pressure.

The fluid that is contained in the manometer is moving towards areas of low pressure. This means they are going to areas with high velocity.

The areas that have low cross sections would flow with a constant rate. This venturi would have low pressure because it has low cross sectional area.

The fluid in the device would then have to move from bottom to top towards the neck of the mercury.

Tensile stress in a thin wall spherical shell is given by

σ = ( p r ) /2t

This is the type of stress that involves pulling out. it is the opposite of compressive stress.

The tensile stress, σ  at the circumference of the shell is the hoop stress. The value equals that of pressure acting on the area.

Therefore:

σ * 2πr * t = p * πr^2

where

2πr = circumference of a circle

πr^2 = area of a circle

p = internal pressure

t = thickness

σ * 2πr * t = p * πr^2

By using the concept of heat transfer, we need to add 0.045kg or 45g of ice to the glass of water to cool it from 20∘C to 0∘C.

The heat lost by the water is equal to the heat gained by the ice cubes. We can use the following equation to calculate the heat transfer:

Q = m_w * c_w * ΔT + m_i * L_f

where Q is the heat transfer, m_w is the mass of water, c_w is the specific heat of water, ΔT is the temperature change (20-0 = 20∘C), m_i is the mass of ice, and L_f is the latent heat of fusion of ice.

We know the values of m_w (0.45kg), c_w (4.18kJ/kg⋅∘C), ΔT (20∘C), and L_f (334kJ/kg). We can rearrange the equation to solve for m_i:

m_i = (Q - m_w * c_w * ΔT) / L_f

Substituting the values, we get:

m_i = [(0.45kg) * (4.18kJ/kg⋅∘C) * (20∘C) - 0] / (334kJ/kg

m_i = 0.045kg
