The compression ratio in an air-standard Otto cycle is 8. At the beginning of the compression stroke the pressure is 14.7 lbf/in2 and the temperature is 600F. The heat transfer to the air during the combustion process per cycle is 800 Btu/lbm. Determine: (a) The pressure and temperature at the end of each process of the cycle. (b) The thermal efficiency (use k = 1.4, Cv = 0.171 Btu/lbm 0F).
