Problem
1. A diesel engine has air before compression at 280 K, 85 kPa. The highest temperature is 2200 K and the highest pressure is 6 MPa. Find the volumetric compression ratio and the mean effective pressure using cold air properties at 300 K.
2. Consider an ideal air-standard diesel cycle in which the state before the compression process is 95 kPa, 290 K and the compression ratio is 20. Find the thermal efficiency for a maximum temperature of 2000 K.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
