. The compression ratio of an air-standard Otto cycle is 9.5. Prior to the isentropic compression process, the air is at 100 kPa, 35 C, and 600 cm. The temperature at the end of the isentropic expansion process is 800 K. Using specific heat values at room temperature, determine (a) the highest temperature and pressure in the cycle; (b) the amount of heat transferred in, in kJ; (c) the thermal efficiency; and (d) the mean effective pressure.

2. The compression ratio of an air-standard Otto cycle is 9.5. Prior
to the isentropic compression process, the air is at 100 kPa,
35°C, and 600 cm. The temperature at the end of the isentropic
expansion process is 800 K. Using specific heat values at room
temperature, determine (a) the highest temperature and
pressure in the cycle; (b) the amount of heat transferred in, in
kJ; (c) the thermal efficiency; and (d) the mean effective
pressure.
