Eckert Number

Written by Jerry Ratzlaff on . Posted in Dimensionless Numbers

Eckert number, abbreviated as Ec, is a dimensionless number used to calculate the ratio of the kinetic energy to enthalpy.

 

Eckert Number formula

\(\large{ Ec = \frac{U^2 } {2  \; c \;  \Delta T}   }\)   

Where:

\(\large{ Ec }\) = Eckert number

\(\large{ \Delta T }\) = change in temperature

\(\large{ U }\) = characteristic flow velocity

\(\large{ c }\) = specific heat
