Question: An air standard dual cycle has a compression ratio of 15 and a cutoff ratio of 1.5. At the beginning of compression, p1 = 1

An air standard dual cycle has a compression ratio of 15 and a cutoff ratio of 1.5. At the beginning of compression, p1 = 1 bar and T1 = 290 K. The pressure doubles during the constant volume heat addition process. If the mass of air is 0.5 kg, determine
(a) The net work (Wnet) of the cycle,
(b) The thermal efficiency (ηth) and
(c) The MEP. Use the PG model.
