Answer:
forced convection
Explanation:
When a fan, pump or suction device is used to facilitate convection, the result is forced convection. Everyday examples of this can be seen with air conditioning, central heating, a car radiator using fluid, or a convection oven.

In the figure, particle 1 of mass m1 = 3.1 kg slides rightward along an x axis on a frictionless floor with a speed of 5.0 m/s. When it reaches x = 0, it undergoes a one-dimensional elastic collision with stationary particle 2 of mass m2 = 4.6 kg. When particle 2 then reaches a wall at xw = 79 cm, it bounces from the wall with no loss of speed. At what position on the x-axis does particle 2 then collide with particle 1?
Answer:
We use Eq 9−67 and 9−68 to find the velocities of the particles after their first collision (at x=0 and t=0 )

and particle 2 is " gaining " at a rate of (10/7)m/s leftward ; this is their relative velocity at that time . Thus , this "gap" of 23cm between them will be closed after an additional time of (0.23m)/(10/7m/s)=0.16s has passed . At this time (t=0.82+0.16=0.98s) the two particles are at x=(−2/7)(0.98)=−28cm

As an engineer you are responsible for selecting and procuring pump for your water distribution system. After some background study you selected and purchased an 1160 rpm Taco 4013 FI and CI series pumps with a 12.75 impeller diameter (for details see the ppt slides for the pump chapter). After procuring the pump you realize that you should have purchased a similar pump but with a 2000 rpm.
Required:
a. What will be your approach to handle this situation?
b. How would you prepare a performance curve at 2000 rpm?
Engineer It A water heater is a tank in which cold water is heated. Cold water flows into the tank to keep it full. A heating element warms the water inside the tank. The heated water can then be sent to hot water faucets in a building. Assume that a water heater design requires the hottest water possible to be sent to hot water faucets in a building. Where would be the best place for the hot water outlet pipe to be attached to the tank: the top, the middle, or the bottom of the tank? Explain your answer.
Answer:
i think it would be the top, the hotter the water the more pressure and sense pressure builds at the top of water heater tanks you would want the outlet pipe at the top
Explanation:
I think it would be the top, the hotter the water the more pressure and sense pressure builds at the top of water heater tanks you would want the outlet pipe at the top.
What is Heater?The process of transforming electrical current into heat energy is known as electric heating. An electrical resistor serves as the heating element in an electric heater, and heat is generated there when an electric current flows through it.
This procedure is frequently utilized in a wide range of domestic applications. from using an electric burner to prepare food, a kettle to boil water, and of course, house heating.
With one significant exception—they don't rely on a boiler and a system of pipes to produce the heat—electric heaters and radiators function exactly like your central heating radiators that are plumbed in.
Therefore, I think it would be the top, the hotter the water the more pressure and sense pressure builds at the top of water heater tanks you would want the outlet pipe at the top.

Curve
Damien can study how the material behaves when immersed by using a; Stress - Strain Curve
To determine the elasticity of a material, we need to find the elastic modulus because the elastic modulus is what quantifies the elasticity of the material.
Now, formula for elastic modulus is;
E = stress/strain
Now, to study the effect on a material's elasticity after it is submerged in water for varying durations, since elasticity is based on the stress and strain on the material, we need to draw a graph of stress vs strain which is also called a stress - strain curve.
The stress strain curve is a graphical tool that helps us know to know the amount of load a material can take before it will stretch and break.

State Conditions necessary for static equilibrium of a particle of a rigid body
Answer:
Conditions for equilibrium require that the sum of all external forces acting on the body is zero (first condition of equilibrium), and the sum of all external torques from external forces is zero (second condition of equilibrium). These two conditions must be simultaneously satisfied in equilibrium.
Hi there!
For a particle to be in static equilibrium:
[tex]\huge\boxed{\Sigma \tau = 0}}[/tex]
The sum of torques acting on the particle must equal 0 Nm.
[tex]\huge\boxed{\Sigma F = 0}}[/tex]
The sum of forces acting on the particle must equal 0 N.
Both of these conditions MUST be met in order for a particle to be in STATIC equilibrium.
