An ideal otto cycle starts a pressure of 100 kpa before the compression and a temperature of 300 K. The compression ratio is 8 and 600 kJ/kg heat is added during the combustion. Considering the specific heat is constant, Specific heat of air at 300 K: $C_v = 0.718$ KJ/(kg K), $C_p = 1.005$ KJ/(kg·K). Please calculate the thermal efficiency $\eta$, P3 and MEP (Mean Effective Pressure) (R=0.287 (kJ/(kg·K)) P 3 $q_{in}$ $\Delta S=0$ 4 2 $\Delta S=0$ $q_{out}$ 1 $V_{min}$ $V_{max}$ V
