The pressure and temperature at the beginning of compression in a Diesel cycle are 100 kPa and 300 K, respectively. At the end of the heat addition, the pressure is 5 MPa and the temperature is 2500 K. Assume that the cold air standard assumptions applies and determine:
a) the compression ratio
b) the cutoff ratio
c) the thermal efficiency of the cycle
d) the mean effective pressure (in kPa)
