Air at 100 kPa, 37°C enters an ideal Otto cycle. The peak pressure and temperature in the cycle are 4.6MPa and 1927 °C, respectively. The compression ratio is 6.414. Using an air-standard analysis, determine: a. The internal energy at each part of the cycle: U₁₂ = U₂ = Uz U4 = b. the net work per unit mass b. the cycle thermal efficiency = kJ/kg kJ/kg kJ/kg kJ/kg kJ/kg
