Solved Problem 6.5 - Adiabatic Efficiency of a R134a Compressor

Consider the R134a refrigerator compressor shown below.

Derive all equations used starting from the basic energy equation for a flow system and the equation for adiabatic efficiency of a compressor.

Solution Approach:

Discussion: This is a feasible compressor design - the adiabatic efficiency is higher than we expected however within an acceptable range (less than around 95%),
