Question: Repeat Problem 9-33 using constant specific heats at room temperature. Problem 9-33 An ideal Otto cycle has a compression ratio of 8. At the beginning

Repeat Problem 9-33 using constant specific heats at room temperature.
Problem 9-33
An ideal Otto cycle has a compression ratio of 8. At the beginning of the compression process, air is at 95 kPa and 27oC, and 750 kJ/kg of heat is transferred to air during the constant-volume heat-addition process. Taking into account the variation of specific heats with temperature, determine
(a) The pressure and temperature at the end of the heat- addition process
(b) The net work output
(c) The thermal efficiency
(d) The mean effective pressure for the cycle.
