Transcribed Image Text:

The cycle of a Diesel engine is made up of the following reversible transformations: an isobar AB, an adiabatic BC, an isochore CD and, finally, another adiabatic DA. Now consider a Diesel engine operating with n = 1 moles of an ideal monatomic gas. Furthermore, let VA = 0.010 m, VB = V.Ve=2V,TA-300 K. a) Calculate the work done by the gas in one cycle. b) Calculate the efficiency of the cycle and compare it to the Carnot cycle of a machine operating between two sources having temperatures equal to TB (temperature in state B) and Tb (temperature in state D). c) Calculate the entropy change corresponding to each transformation.
