Eckert Number

Written by Jerry Ratzlaff. Posted in Dimensionless Numbers

Eckert Number is a dimensionless number used to calculate the ratio of the kinetic energy to enthalpy.

FORMULA

\(Ec = \frac{v^2 } {2   v   \triangle T}\)

Where:

\(Ec\) = Eckert Number

\(v\) = flow velocity

\(c\) = specific heat

\(\triangle T\) = temperature differential

Solve for:

\(v =  \sqrt  {  2    Ec   c   \triangle T     }\)

\(c = \frac{v^2 } {2   Ec   \triangle T}\)

\(\triangle T = \frac{v^2 } {2   Ec   c}\)
