Unformatted text preview: 2 and 3 4 are isochoric and the processes 2 3 and 4 1 are adiabatic. (a) Compute the amounts of heat absorbed and discarded by this engine in one cycle, in terms of the temperatures of the turning points, T 1 , T 2 , T 3 , and T 4 , and the constantvolume molar heat capacity of the gas C V . (b) Obtain a formula for the thermal efficiency of the engine in terms of T 1 , T 2 , T 3 , and T 4 . (c) Using the relationship between T and V for an adiabatic process, obtain a formula for the thermal efficiency of the engine in terms of the compression ratio r=V 3 /V 2 and the heat capacity ratio of the gas . #20.53 [Fuel Efficiency of a Volkswagen]...
