Question:

An uninsulated compressor delivers ethylene, C2H4, to a pipe, D 10 cm, at 10.24 MPa, 94C and velocity 30 m/s. The ethylene enters the compressor at 6.4 MPa, 20.5C and the work input required is 300kJ/kg. Find the mass flow rate, the total heat transfer and entropy generation, assuming the surroundings are at 25C.
