A heat engine with a thermal efficiency of 35 percent produces 750kJ of work. Heat transfer to the engine is from a reservoir at 550K, and the heat transfer from the engine to the surrounding air is at 300K. a) Sketch a diagram to represent the heat engine system. b) Determine the heat transfer to and from the heat engine. c) If the heat engine is replaced by a Carnot heat engine producing the same work output, determine the heat transfer to and from the Carnot heat engine
