Otto, Diesel, and Dual Cycles
Solve Problem 9.22 on a cold air-standard basis with specific heats evaluated at 520°R.
9.22 Consider an air-standard Diesel cycle. At the beginning of compression, p1 = 14.0 lbf/in.2 and T1 = 520°R. The mass of air is 0.145 lb and the compression ratio is 17. The maximum temperature in the cycle is 4000°R. Determine
(a) the heat addition, in Btu.
(b) the thermal efficiency.
(c) the cutoff ratio.
