Problem #2 A compressor operating isothermally is to compress 2.83 m³/min of ammonium gas at 29.4°C and 102.7 kPa to 311.6 kPa. (a) Calculate the power required if the efficiency of the compressor is 75%. (b) Repeat the calculation if the compressor is uncooled and determine the outlet temperature*. (c) What is the percentage of power saved from isothermal operation and can this compressor be safely operated without cooling? *Note: y values for NH3 gas: YNH3=1.4.
