A Diesel cycle is running with air as the working fluid which enters at the beginning of the compression stoke at 70◦F and 1atm. It undergoes an isentropic compression process with a compression ratio of 20 (Vmax/Vmin = 20). The volume at bottom dead center (Vmax) is 500in3. Treat air with constant specific heats evaluated at the inlet state for this process.

How much work is done on the fluid (Btu) during the compression process?

Heat is then added to the air by combustion in a constant pressure process. The volume at the end of the heat addition process is 50in3. Treat air with constant specific heats evaluated at 1500◦F for this process.

What would the ideal efficiency for this cycle be using the cold air standard assumption?

How much heat (Btu) is added during the constant pressure heat addition process?
