Solved: The pressure and temperature at the beginning of

Chapter 9, Problem 9.37

(choose chapter or problem)

The pressure and temperature at the beginning of compression in an air-standard dual cycle are \(14.0 \mathrm{lbf} / \mathrm{in}^{2}\) and \(520^{\circ} \mathrm{R}\), respectively. The compression ratio is 15 and the heat addition per unit mass of air is 800 Btu/lb. At the end of the constant volume heat addition process, the pressure is \(1200 \mathrm{lbf} / \mathrm{in}^{2}\) Determine

(a) the net work of the cycle per unit mass of air, in Btu/lb.

(b) the heat rejection for the cycle per unit mass of air, in Btu/lb.

(c) the thermal efficiency.

(d) the cutoff ratio.

(e) To investigate the effects of varying compression ratio, plot each of the quantities calculated in parts (a) through (d) for compression ratios ranging from 10 to 28.
