ME 200: Thermodynamics I Spring 2011 Division 1 Quiz 7 Name Sameer Naik A reversible heat engine operates between two reservoirs at absolute temperatures T H and T C . Work produced by the reversible heat engine is used for driving a reversible refrigeration cycle operating between the same two reservoirs. Thermal efficiency of the reversible heat engine is 20%. Draw a sketch of the system showing all work and heat interactions.
