A Stirling cycle engine uses 0.0800 lbm of air as the working fluid. Heat is added to this air isothermally at 1500.°F and is rejected isothermally at 200.°F. The initial volume of the air before the heat addition ( in given Figure) is 0.750 ft3 and the final volume after the heat addition ( in given Figure) is 1.00 ft3 . For the cold ASC, determine
a. The air pressure at the beginning and end of the expansion stroke (p4 and p1 in Figure 13.38).
b. The air pressure at the beginning and end of the compression stroke (p2 and p3 in Figure 13.38).
c. The cold ASC thermal efficiency of the engine.
d. The net reversible work produced inside the engine per cycle of operation.
