Repeat Problem 9-46 using constant specific heats at room temperature.
Problem 9-46
An air-standard Diesel cycle has a compression ratio of 16 and a cutoff ratio of 2. At the beginning of the compression process, air is at 95 kPa and 27oC. Accounting for the variation of specific heats with temperature, determine
(a) The temperature after the heat-addition process
(b) The thermal efficiency
(c) The mean effective pressure.
