Carbon dioxide (CO2) as an ideal gas executes a Carnot power cycle while operating between thermal reservoirs at 450 and 1008F. The pressures at the initial and final states of the isothermal expansion are 400 and 200 lbf/in.2, respectively. The specific heat ratio is 5 1.24. Using the results of Problem 5.80 as needed, determine

(a) the work and heat transfer for each of the four processes, in Btu/lb.

(b) the thermal efficiency.

(c) the pressures at the initial and final states of the isothermal compression, in lbf/in.2
