122 - 04-01-a - efficiency and Carnot efficiency: engine schematic
Definition of efficiency and the 1st law of thermodynamics (the latter is used to eliminate W),
Thus the efficiency cannot be greater than 1, and can equal 1 only if . However, there is a stronger bound on efficiency beyond that imposed by conservation,
This is called the Carnot efficiency.
