# The compression ratio of an air-standard Otto cycle is 9.5

This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

The compression ratio of an air-standard Otto cycle is 9.5. Prior to the isentropic compression process, the air is at 100 kPa, 17 C, and 600 cm2. The temperature at the end of the isentropic expansion process is 800K. Using specific heat value at room temperature, determine:

1. The highest temperature and pressure in the cycle
2. The amount of heat transferred, in kJ
3. The thermal efficiency
4. The mean effective pressure

Show the cycle on P-v diagram and state all assumptions and show units.
