A water cooled compressor changes the state of R-134a from a saturated vapor at 15 psia to a pressure of 120 psia. The fluid rate is 2.0 lbm/min, and the cooling water removes heat at a rate of 135 Btu/min. If the power input is 4.0 hp, determine the exit temperature [F]. Show the process on a T-v state diagram. Assume steady state - steady flow. Also neglect kinetic and potential energy effects.
