The pressure and temperature at the beginning of compression of an air-standard diesel cycle are 100 kpa and 300 k, respectively. at the end of the heat addition, the pressure is 6.8 mpa and the temperature is 2000 k (a) sketch the p-v and t-s diagrams (b) determine the compression ratio and cutoff ratio (c) determine the thermal efficiency of the cycle, in %. (d) determine the mean effective pressure, in bar.
