An air-standard Diesel cycle operates with a compression ratio of 18. At the beginning of the compression process, the pressure and temperature are P1 = 0.1 MPa and T1 = 300 K. The cut-off ratio for the cycle is 2. Determine:
(a) the temperature and pressure at the end of each process of the cycle,
(b) the thermal efficiency, and
(c) the mean effective pressure, in MPa.
