Question

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 27°C. Accounting for the variation of specific heats with temperature, determine (a) the temperature after the heat- addition process,(b) the thermal efficiency, and (c) the mean effective pressure. (Put in thermal efficiency as answer in percent)
