A note on the overall efficiency of back-to-back Carnot cycles

The overall efficiency of a reversible thermodynamic cycle comprising steps around the periphery of back-to-back Carnot cycles is equal to the efficiency-weighted average heat-energy inputs taken over all of the cycles. A proof of this assertion is straightforward and brief enough to be suitable for...

Description
Summary:The overall efficiency of a reversible thermodynamic cycle comprising steps around the periphery of back-to-back Carnot cycles is equal to the efficiency-weighted average heat-energy inputs taken over all of the cycles. A proof of this assertion is straightforward and brief enough to be suitable for classroom presentation.
