Question

An ideal diesel engine has a compression ratio of 25 and uses air as the working fluid. The state of air at the beginning of the compression is 105 kPa

and 30°C. If the amount of heat addition during the constant pressure process is (125 + 0.25 * the last 2 digits of your student ID) kJ/kg, using the air standard assumption determine a. The maximum temperature of the cycle b. Cut-off ratio of the cycle c. The thermal efficiency of the cycle d. Work-nett produced by the cycle e. The mean effective pressure (MEP) OF the cycle f. The amount of heat rejected to the environment.
