• Sketch and labels the P-v and T-s diagrams of the following processes: 1-2: Isentropic compression with a compression ratio, r = V1/V2 2-3: Constant volume heat addition with a pressure ratio, rp = P3/P2 3-4: Constant pressure heat addition with a volume ratio, rc = V3/V2 4-5: Isentropic expansion while work is done until V5 = V1 5-1: Constant volume heat rejection to initial state
