Consider the compression step of an ordinary vapor compression cycle using ammonia as the working fluid. The inlet to the compressor is saturated vapor at 10 C and approximately 6.25 bar, the outlet is superheated vapor at 10 bar. Approximate the non-ideal PVT-behavior of ammonia in this region by the van der WaalââŹâ˘s EOS. Using the data Tc = 132.4 C, Pc=112.8 bar, and Cv=36.1 kJ/kmol-K (and no other data).
Required:
Derive a set of equations that can be solved simultaneously for the temperature of the outlet stream, assuming the compressor is reversible.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
