Problem 5 [TOTAL: 7.0 Points] The mean effective pressure of an ideal Diesel cycle is 8 bar. If the initial pressure is 1.03 bar and the compression ratio is 12, determine the cut-off ratio and the air-standard efficiency. Assume ratio of specific heats for air to be 1.4. The air standard diesel cycle efficiency is given by n-1- -1 (-1) where 'r' is the compression ratio and 'r' is the cut off ratio
