Answer:
D. a measure of how fast a machine performs work
Explanation:
Power can be defined as the energy required to do work per unit time.
Mathematically, it is given by the formula;
Hence, the best description of power is that, it is a measure of how fast a machine performs work.
This can be calculated by using the mathematical expression below;

But we know that,
Answer: hello your question lacks the required diagram attached below is the diagram
answer : 29528.1 N/m^2
Explanation:
Given data :
dimensions of tank :
Length = 5-m
Width = 4-m
Depth = 2.5-m
acceleration of tank = 2m/s^2
<u>Determine the maximum gage pressure in the tank</u>
Pa ( pressure at point A ) = s*g*h1
= 10^3 * 9.81 * 3.01
= 29528.1 N/m^2
attached below is the remaining part of the solution
Answer:
When an alternative refrigerant is mixed with R-22, there is no pressure-temperature chart to refer to and therefore no way to optimize the system charge. Improper superheat or subcooling can lead to compressor floodback, overheating, and dramatically reduce system efficiency and compressor lifetime
