Question

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 760 kJ/kg of heat is

transferred to air during the constant-volume heat-addition process. Take into account the variation of specific heats with temperature. The gas constant of air is R= 0.287 kJ/kg-K. Determine the pressure and temperature at the end of the heat-addition process. (You must provide an answer before moving on to the next part.) The pressure at the end of the heat-addition process is_______kPa. The temperature at the end of the heat-addition process is______kPa.
