An air-standard Diesel cycle has a compression ratio of 16 and cutoff ratio of 2. At the beginning of the compression process, air is at 95kPa and 27°C. 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

d) The pressure at the beginning of the constant-volume heat rejection process
