Using your computer solution from Problem 8.60, vary the pressure ratio from 1 (no compressor) to 40.
Question:
Using your computer solution from Problem 8.60, vary the pressure ratio from 1 (no compressor) to 40. Plot the outflow temperature and the compressor power as a function of the pressure ratio. Put the pressure ratio on the abscissa (x-axis).
Problem 8.60
A vertical cylinder–piston arrangement contains 0.3 lbm of H2O (liquid and vapor in equilibrium) at 120 F, as shown in the sketch for the previous problem. Initially, the piston rests on the stops, and the volume beneath the 250-lbm piston is 1.054 ft3. The piston area is 120 in2. The atmospheric pressure is 14.7 lbf /in2, and the gravitational acceleration is 30.0 ft/s2. Heat is transferred to the arrangement until only saturated vapor exists inside.
