Coefficient of performance, or COP, is defined differently for heating and cooling applications. For heating:
COP=(heat supplied + work)/work
For cooling:
COP=(heat removed)/work
Work in this case refers to the compressor and other motors.
what the relation between electric power & cofficient of performance
When you plot a system on a mollier diagram it the point between the pressure drop and the bottom of the compression line, measured in BTU/LB. Also known as the Net Refrigeration Effect.

Coefficient of discharge of an ideal liquid can be defined as a ratio of actual discharge and theoretical discharge. where, Cofficient of discharge = Actual Discharge/ Theoretical discharge.
The system analyst is considered to be a change agent because he can analyze what parts of the system need to be improved. The system analyst can recommend upgrades to a system and compare them for performance differences.
(a) Cost is minimized when building a network using BF algo. (b) Maximizes the performance of the system. Also finds min path weight . (c) It allows splitting of traffic between several paths. It thus increases system performance.
COPR a measure of the performance let's take a look at another system that is surprisingly similar to a refrigerator.

why correlation cofficient always lies between 1 and -1
In practical applications, vapor-compression refrigeration systems are the most commonly used refrigeration systems, and each system employs a compressor. In a basic vapor compression refrigeration cycle as shown in Figure 3.28, four major thermal processes take place as follows: • evaporation, • compression, • condensation, and • expansion.

An evaporator in a refrigeration system works by passing warm air over it's coils.
That 5 is the cofficient of the term. The "n" is the variable!
