Calculate the heat transfer for the process described in Problem 4.30. A cylinder containing 1 kg of ammonia has an externally loaded piston. Initially the ammonia is at 2 MPa, 180C and is now cooled to saturated vapor at 40C, and then further cooled to 20C, at which point the quality is 50%. Find the total work for the process, assuming a piecewise linear variation of P versus V.
