<h2>Answer: 540 J</h2>
Explanation:
The Work done by a Force
refers to the release of potential energy from a body that is moved by the application of that force to overcome a resistance along a path.
Now, when the applied force is constant and the direction of the force and the direction of the movement are parallel, the equation to calculate it is:
(1)
In this case both (the force and the distance in the path) are parallel (this means they are in the same direction), so the work performed is the product of the force exerted to push the box
by the distance traveled
.
Hence:
(2)
Answer:
2.25in³
Explanation:
For a 12 awg conductor the minimum volume allowance as stated by the NEC is 2.25in³
See attached Table 314.16(B) from NEC 2011
Answer:L=109.16 m
Explanation:
Given
initial temperature
Final Temperature
mass flow rate of cold fluid
Initial Geothermal water temperature
Let final Temperature be T
mass flow rate of geothermal water
diameter of inner wall
specific heat of water
balancing energy
Heat lost by hot fluid=heat gained by cold Fluid
As heat exchanger is counter flow therefore
heat lost or gain by Fluid is equal to heat transfer in the heat exchanger
(LMTD)
