14. In an air-standard Otto cycle, the compression _ratio is 10. The condition at the beginning of the compression process is 100 kPa and 27C. Heat added at constant volume is 1500 kJ/kg, while 700 kJ/kg of heat is rejected during the other constant volume process in the cycle. (Specific gas constant for air = 0.287 kJ/kg K) The mean effective pressure (in kPa) of the arth cycle is - 14. In an air-standard Otto cycle, the compression _ratio is 10.
