An air-standard dual cycle has a compression ratio of 14. At the beginning of compression, p1 = 14.5 lbf/in.2, V1 = 0.5 ft3, and T1 = 50°F. The pressure doubles during the constant-volume heat addition process. For a maximum cycle temperature of 3000°R, determine: (a) the heat addition to the cycle, in Btu. (b) the net work of the cycle, in Btu. (c) the percent thermal efficiency. (d) the mean effective pressure, in lbf/in.2

Question

An air-standard dual cycle has a compression ratio of 14. At the beginning of compression, p1 = 14.5 lbf/in.2V1 = 0.5 ft3, and T1 = 50°F. The pressure doubles during the constant-volume heat addition process.


For a maximum cycle temperature of 3000°R, determine:
(a) the heat addition to the cycle, in Btu.
(b) the net work of the cycle, in Btu.
(c) the percent thermal efficiency.
(d) the mean effective pressure, in lbf/in.2
