We define the thermal efficiency<\/strong>, \u03b7<\/em><\/strong>th<\/sub><\/em><\/strong>, of any heat engine as the ratio of the work<\/a> it does, W<\/strong>, to the heat<\/a> input at the high temperature, QH<\/sub>.<\/p>\n <\/a><\/p>\n The thermal efficiency<\/strong>, \u03b7<\/em><\/strong>th<\/sub><\/em><\/strong>, represents the fraction of heat<\/strong>, QH<\/sub><\/strong>, converted to work<\/strong>. It is a dimensionless performance measure of a heat engine that uses thermal energy, such as a steam turbine, an internal combustion engine, or a refrigerator.<\/p>\n Carnot\u2019s rule:<\/a><\/b><\/strong><\/p>\nKey Facts<\/h3>\n
