Question

Use EES to solve this problem, include code and plots. An ideal diesel engine uses air as the working fluid. The state of the air at the beginning of the compression process is 95 kPa and 20\deg C. If the maximum temperature of the cycle is not to exceed 2200 K, determinethe thermal efficiency andw_netas a function of compression ratio, r. Vary the compression ratio from 14 to 24 in steps of 2 (e.g., 14, 16, 18, etc.)Do not use constant specific heats. Use function calls to get the needed values in your COE equations.Plot the net work output and thermal efficiency as a function of compression ratio on separate plots. You can plot in EES Or excel
