Question: A Carnot engine operates between two heat reservoirs at temperatures TH and TC . An inventor proposes to increase the efficiency by running one engine

A Carnot engine operates between two heat reservoirs at temperatures TH and TC

.

An inventor proposes to increase the efficiency by running one engine between TH and an intermediate temperature T and a second engine between T and TC using as input the heat expelled by the first engine. Compute the efficiency of this composite system. Compare the efficiency of this composite system to that of the original engine.
