Required information An ideal Otto cycle has a compression ratio of 8. At the beginning of the compression process, air is at 95 kPa and 27°C, and 730 kJ/kg of heat is transferred to air during the constant-volume heat-addition process. Take into account constant specific heats at room temperature. The properties of air at room temperature are cp=1.005 kJ/kg-K, cy=0.718 kJ/kg-K, R= 0.287 kJ/kg-K, and k = 1.4. Determine the mean effective pressure for the cycle. The mean effective pressure for the cycle is 618.25 kPa.

Required information
An ideal Otto cycle has a compression ratio of 8. At the beginning of the compression process, air is at 95 kPa
and 27°C, and 730 kJ/kg of heat is transferred to air during the constant-volume heat-addition process. Take into
account constant specific heats at room temperature. The properties of air at room temperature are cp=1.005 kJ/kg-K,
cy=0.718 kJ/kg-K, R= 0.287 kJ/kg-K, and k = 1.4.
Determine the mean effective pressure for the cycle.
The mean effective pressure for the cycle is 618.25 kPa.
