Question

Determine using the attached Form... Please show work.


The compression ratio of an air-standard Otto cycle is 8. Prior to the isentropic compression process, the air is at 150kPa, 27 degrees C, and 400 cm^3. The temperature at the end of the isentropic expansion process is 700K. 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
