A compressor in an industrial air-conditioner compresses ammonia from a state of saturated vapor at 200 kPa
Question:
A compressor in an industrial air-conditioner compresses ammonia from a state of saturated vapor at 200 kPa to a pressure 800 kPa. At the exit, the temperature is measured to be 100◦C and the mass flow rate is 0.5 kg/s. What is the required motor size for this compressor and what is its isentropic efficiency?
