Applications of Carnot Cycles
We stated:
Any cyclic process that absorbs heat at one temperature, and rejects heat at one other temperature, and is reversible has the energy efficiency of a Carnot cycle.
Why did we calculate energy efficiencies for
Because:
they are not 2-temperature devices, but accept and reject heat at a range of temperatures
Energy efficiency not given by the Carnot formula
But:
It is interesting to compare the maximum possible efficiency of a Carnot cycle with the efficiency of engineering cycles with the same maximum and minimum temperatures.
