Determine the total exergy destruction associated with the Diesel cycle described in Problem 9-46, assuming a source temperature of 2000 K and a sink temperature of 300 K. Also, determine the energy at the end of the isentropic compression process.
Problem 9-46:
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.
