Saturated water vapor at 300°f enters a compressor operating at steady state with a mass flow rate of 5 lb/s and is compressed adiabatically to 800 lbf/in.2 if the power input is 2150 hp, determine for the compressor: (a) the percent isentropic compressor efficiency and (b) the rate of entropy production, in hp/°r. ignore kinetic and potential energy effects.

oil flow is a highly convective flow compared to water flow at normal temperature and pressure.

how is this a question? in order for me to answer it i have to understand the question
