One lb of air undergoes a power cycle consisting of the following processes: Process 1-2: Constant volume from p1=20 lbf/in2, T1=500 oR to T2=820 oR Process 2-3: Adiabatic Expansion to v3=1.4 v2 Process 3-1: constant pressure compression Sketch the cycle on a p-v diagram. Assuming ideal gas behavior, determine: (a) The pressure at state 2, in lbf/in2 (b) The temperature at state 3, in oR (c) The total amount of heat transfer for the cycle (d) The total amount of work for the cycle
