Repeat Prob. 9-52E using constant specific heats at room temperature.
Prob. 9-52E
An air-standard Diesel cycle has a compression ratio of 18.2. Air is at 1208F and 14.7 psia at the beginning of the compression process and at 3200 R at the end of the heat addition process. Accounting for the variation of specific heats with temperature, determine
(a) The cutoff ratio
(b) The heat rejection per unit mass
(c) The thermal efficiency.
