2. Two and one-half pounds of air actuate a cycle composed of the following processes: polytropic compression 1-2, with n=1.5; constant pressure 2-3; constant volume 3-1. The known data are: p1 = 20psia, t1 = 100degF, Qr = -1682 Btu. Determine a) T2 and T3, b) the work of the cycle using the pV plane, in Btu; c) Qa, d) the thermal efficiency and e) pm.
