Physics

During the power stroke in a four-stroke automobile engine, thepis-ton is forced down as the mixture of combustion products andair undergoes an adiabatic expansion. Assume (1) the engine isrunning at 2500 cycles/min; (2) the pressure immediately before theexpansion is 20.0 atm; (3) the volumes of the mixture immediatelybefore and after the expansion are 50.0 cm3and 400 cm3,respectively ; (4) the time interval for expansion is one-fourththat of the total cycle; and (5) the mixture behaves like an idealgas with specific heat ratio 1.40. Find the average power generatedduring the power stroke.
