Draw and label the P-V and T-S diagrams. Given an ideal diesel cycle with compression ratio of 16.2, cut-off ratio of 2.05, Determine the mean effective pressure if the initial pressure is 14.71 psi.

! Required information An air-standard Diesel cycle has a compression ratio of 16 and a cutoff ratio of 2. At the beginning of the compression process, air is at 101.0 kPa and 27°C. Account for the variation of specific heats with temperature. The gas constant of air is R = 0.287 kJ/kg.K. Determine the thermal efficiency. The thermal efficiency is %.

Required information An air-standard Diesel cycle has a compression ratio of 16 and a cutoff ratio of 2. At the beginning of the compression process, air is at 95 kPa and 27°C. Account for the variation of specific heats with temperature. The gas constant of air is R = 0.287 kJ/kg-K. Determine the thermal efficiency. (You must provide an answer before moving on to the next part.) The thermal efficiency is %
