[QUOTE="Peter Jones, post: 6486224, member: 683981"] [B]Homework Statement:[/B] A combination of steam mercury turbines, includes two stages. The first stage runs on saturated mercury vapour at 876°F and emits heat to heat a boiler at 460°F. The vapour in this boiler is used to run a second stage of the turbine, and emits heat to a steam condenser chamber which is at 100°F. Find the maximum efficiency of this combination [B]Relevant Equations:[/B] Carnot efficiency H=1-T2/T1 I think it reaches its maximum efficiency when it is two continuous Carnot process. Its efficiency then will be H= 1-(W1+W2)/(Q1+Q2), with W1/Q1>=T2/T1 and W2/Q2>=T3/T2 therefore H<= 1- (Q1.T2/T1+Q2.T3/T2)/(Q1+Q2), that is as far as i can go, have not got a result yet [/QUOTE]
