An ideal Otto cycle has a compression ratio of 8. At thebeginning of the compression process, air is at 95 kPa and 27°C,and 730 kJ/kg of heat is transferred to air during theconstant-volume heat-addition process. Take into account thevariation of specific heats with temperature. The gas constant ofair is R = 0.287 kJ/kg·K.
Determine:
(a) the pressure and temperature at the end of the heat additionprocess
(b) the net work output
(c) the thermal efficiency
(d) the mean effective pressure for the cycle.
