The pressure and temperature at the beginning of compression of an air-standard diesel cycle are 100 kpa and 100 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.
