carnot efficiencymedical dictionary

<radiobiology> Maximum possible efficiency for conversion of thermal energy to useful work (such as electrical energy), as determined by the laws of thermodynamics. The Carnot efficiency (eta) for conversion of thermal to electric energy (for example, the upper limit on efficiency of a steam turbine) is given by (eta) = [ (T-hot) - (T-cold) ] / (T-hot). That is, one gets the efficiency from the values of the input and output temperatures (measured in Kelvin).
