Saturated ammonia at a temperature of 50oF and a flow rate of 3 lbm/s enters a steady-state well-insulated device with an isentropic efficiency of 85%. The device needs to increase the pressure of the ammonia to 200 psia. Calculate the power required (in hp) and the exit temperature (in oF) if a) The device is a compressor and the ammonia is saturated vapor. b) The device is a pump and the ammonia is saturated liquid
