Using Energy Concepts and the Ideal Gas Model

One lb of oxygen, O2, undergoes a power cycle consisting of the following processes:

Process 1–2: Constant-volume heating from p1 = 20 lbf/in.2, T1 = 500°R to T2 = 820°R.

Process 2–3: Adiabatic expansion to v3 = 1.432v2.

Process 3–1: Constant-pressure compression to state 1.

Sketch the cycle on a pv diagram. Assuming ideal gas behavior, determine

(a) the pressure at state 2, in lbf/in.2

(b) the temperature at state 3, in °R.

(c) the heat transfer and work, each in Btu, for all processes.

(d) the thermal efficiency of the cycle.
