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 780 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, cv = 0.718 kj/kg·k, r = 0.287 kj/kg·k, and k = 1.4. 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.
