Diesel Cycle Revision + Comparison

An ideal Diesel cycle with air as the working fluid has a compression ratio of 18 and a cutoff ratio of 2. At the beginning of the compression process, the working fluid is at 100 kPa, 27°C, and 1917 cm3

.

Using the THREE different methods, detennine: The maximum temperature and pressure that occur during the cycle, the net work output, the thermal efficiency, and the mean effective pressure for the cycle.
