Question
The system below uses two heat engines, where the waste heat from HE1 is used as the
heat source for HE2.
a) Find the overall efficiency of the system shown below as a function of the two
individual efficiencies. In other words, find n overail =f(n1,n2).
b) Based on part a, can the efficiency of the two heat engines ever be greater than
100%? If multiple (infinite?) heat engines are chained together in the same way, so that each
heat engine is powered by the waste heat of the one before it, can the overall efficiency ever
be greater than 100%?
