As compared to air standard cycle, in actual working, the effect of variation in specific heats is to
A. Increase maximum pressure and maximum temperature
B. Reduce maximum pressure and maximum temperature
C. Increase maximum pressure and decrease maximum temperature
D. Decrease maximum pressure and increase maximum temperature
Answer: Option B
Solution (By Examveda Team)
As compared to air standard cycle, in actual working, the effect of variation in specific heats is to Reduce maximum pressure and maximum temperatureThis Question Belongs to Mechanical Engineering >> Internal Combustion Engines (I.C. Engines)
air standard cycle is the otto cycle isentropic compression but in actual not reversible adiabatic expansion due to friction thus loss of temp and pressure in the actual cycle
