Carnot Efficiency

Written by Jerry Ratzlaff on . Posted in Dimensionless Numbers

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

 

Carnot efficiency formula

\(\large{ n_c = 1 - \frac{ T_c }{ T_h } }\) 

\(\large{ n_c =  \frac{ T_h \;-\; T_c }{ T_h } \;100 }\)

Symbol English Metric
\(\large{ n_c }\) = Carnot efficiency   \(\large{dimensionless}\)
 \(\large{ T_c }\) = absolute temperature of cold source \(\large{F}\) \(\large{K}\)
\(\large{ T_h }\) = absolute temperature of hot source  \(\large{F}\) \(\large{K}\)
