Thermal Efficiency

Written by Jerry Ratzlaff on . Posted in Thermodynamics

Thermal efficiency, abbreviated as \(\eta_{th}\) (Greek symbol eta), is the fraction of heat that is converted to work or desired output divided by required input.


Thermal efficiency Formula

\(\large{ \eta_{th}  =  \frac{ W }{ Q_n }  }\)   


\(\large{ \eta_{th} }\)  (Greek symbol eta) = thermal efficiency

\(\large{ Q_n }\) = total energy input from hot source

\(\large{ W }\) = work
