An ideal dual cycle has a compression ratio of 15 and a cutoff ratio of 1.4. The pressure ratio during constantvolume heat addition process is 1.1. The state of the air at the beginning of the compression is P1 = 14.2 psia and T1 = 75℉. Calculate the cycle’s net specific work, specific heat addition, and thermal efficiency. Use constant specific heats at room temperature.
