---a heat engine operates between two heat reservoirs with temperature of 560 and 280 K. The thermal efficiency of the actual unit is 0.40, the engine itself receives heat at 540 K and reject heat at 300 K.

Determine the entropy production rate, in kJ/min. K for the heat engine itself the low temperature heat transfer process, and the high temperature heat transfer process then which process has the largest irreversibility?
