A. An air standard Diesel cycle rejects 10 KJ per cycle of heat while operating at 300 rpm. At the beginning of compression, pressure is 98 KPaa and temperature = 30 deg C, volume is 0.046 cu. meter. At the beginning of heat addition, pressure is 3500 KPaa. Determine the following in the Table below (fill up this sheet with your answers, or write a summary of your answers and show your solution in separate sheets): Item 1. PV and TS diagrams 2. PVT values at each point in the cycle, see Table below. 3. Compression ratio 4. Cut-off ratio 5.
