Question

The pressure and temperature at the beginning of compression of a cold air-standard Diesel cycle are 95 kPa and 300 K, respectively. At the end of the heat addition, the pressure is 7.2 MPa and the temperature is 2050 K. Assume constant specific heats evaluated at 300 K.


Determine:

(a) the compression ratio.

(b) the cutoff ratio.

(c) the percent thermal efficiency of the cycle.

(d) the mean effective pressure, in kPa.
