Power Cycle Thermal Efficiency

Efficiency is a general concept used to describe the effectiveness of energy conversion from one state or form to another. Thermodynamic efficiency and coefficient of performance (COP) are terms used for expressing efficiency for devices that operate in cycles or for individual system components that operate in processes. The term COP is usually reserved for refrigeration systems. The thermal efficiency of a cycle is the ratio of output energy to input energy. In a heat engine, the desired form of energy is the work; the form of energy that costs money is heat from the high-temperature source (directly or indirectly, the cost of the fuel).
