Assume that an actual compressor has the same exit pressure and specific heat transfer as the ideal isothermal compressor in Problem 7.27, with an isothermal efficiency of 80%. Find the specific work and exit temperature for the actual compressor.
Problem 7.27
A compressor is surrounded by cold R-134a, so it works as an isothermal compressor. The inlet state is 0?C, 100 kPa and the exit state is saturated vapor. Find the specific heat transfer and the specific work.
