Carnot corollaries n<100%>what's the maximum theoretical efficiency? Less work 7 The thermal efficiency of an irreversible power cycle is always less than the thermal efficiency of a reversible power cycle when each operates between the same two thermal reservoirs. Not“same△Tk- All reversible power cycles operating between the same two thermal reservoirs have the same thermal efficiency.
