Carnot Efficiency

Written by Jerry Ratzlaff on . Posted in Dimensionless Numbers

Carnot efficiency, abbreviated as \(n_{max}\), a dimensionless number, is the theroetical maximum efficiency of any heat engine depending only on the temperatures it operates between.

 

Carnot efficiency formula

\(\large{ n_{max} = 1 \;-\; \frac{ T_c }{ T_h }    }\)   

Where:

\(\large{ n_{max} }\) = Carnot efficiency

\(\large{ T_c }\) = absolute temperature of cold source

\(\large{ T_h }\) = absolute temperature of hot source
