Question

An air-standard cycle with variable specific heats is executed in a closed system and is composed of the following four processes: 1-2 Isentropic compression from 100 kPa and $22^{\circ} \mathrm{C}$ to 600 kPa, 2-3 v = constant heat addition to 1500 K, 3-4 Isentropic expansion to 100 kPa, 4-1 P = constant heat rejection to initial state. (a) Show the cycle on P-v and T-s diagrams. (b) Calculate the net work output per unit mass. (c) Determine the thermal efficiency.
