an engine operates on the carnot cycle between the temperature limits of 250c and 50c. the pressure and the volume at the start of the isothermal expansion are 6 bar and 0.1 m^3 respectively. pressure after isothermal expansion is 3 bar. assume gamma=1.4,R=0.287kj/kg.k

calculate the efficiency of cycle
,output work and change in entropy of each process?
