Find the mass flow rate and the total heat transfer

Question

Problem

1. Rework the previous problem using an evaporator temperature of 0^oC.

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

The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
