The conditions at the beginning of compression in an air-standard Diesel cycle are fixed by p1=200kPa, T1=380K. The compression ratio is 20 and cutoff ratio is 1.8. If the air is treated as ideal gas and it has a constant specific heat ratio of 1.4, determine: 1) The maximum temperature 2) The heat addition per unit mass 3) The net work per unit mass 4) The thermal efficiency 5) The mean effective pressure.
