Determine the total exergy destruction associated with the Diesel cycle described in Problem 9-46, assuming a source

Question:

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.
