The following problem corresponds to a R-134a compressor operating under steady-flow, under two different situations. For both situations the inlet is saturated vapor at 160 kPa and the volume flow rate is 2 m3 /min. Also the desired exit pressure is 900 kPa Situation I: The compressor operates in an adiabatic reversible manner. Situation II: The compressor operates adiabatically. The power supplied to the compressor is 20% larger than the one corresponding to Situation I. Please answer the following. a. For Situation I, compute the power needed by the compressor, in kW. Draw a schematic of your system and list the assumptions you used in your solution. b. For Situation I, determine the specific entropy at the exit, in kJ/kg-K c. For Situation I, compute the net rate of entropy through the compressor due to the mass flow, in kW/K, and the rate of entropy generated expressed in its corresponding units. d. For Situation II, compute the power needed by the compressor, in kW. Draw a schematic of your system and list the assumptions you used in your solution. e. For Situation II, determine the specific entropy at the exit, in kJ/kg-K. Hint: compute the exit enthalpy to pin the exit state, recall that the pressure at the exit is known. f. For Situation II, compute the net rate of entropy through the compressor due to the m
