The pressure and temperature at the beginning of compression of an 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 2150 k. determine (a) the compression ratio. (b) the cutoff ratio. (c) the thermal efficiency of the cycle. (d) the mean effective pressure, in kpa.
