Asix-cylinder, four-stroke, 3.2-l compression-ignition engine operates on the ideal diesel cycle with a compression ratio of 19. the air is at 95 kpa and 67 degrees celcius at the beginning of the compression process and the engine speed is 1750 rpm. the maximum temperature is 2200 k. using constant specific heats at 850 k, determine (a) the cutoff ratio (b) the net work output per cycle and the thermal efficiency, (c) the mean effective pressure, (d) the net power output.
