(a) Determine the compression ratio and the thermal efficiency ... | Filo

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 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, and (d) the mean effective pressure for the cycle. | Numerade
