Colburn-Chilton j factor

Colburn-Chilton j factor is used in heat transfer in general and free and forced convection calculations in particular. It is equivalent to (St.Pr^2/3). It is normally defined in one of the following forms :

 

Colburn-Chilton j factorColburn-Chilton j factor

or

Colburn-Chilton j factor

 

Where:

Cp

=

Heat capacity

G

=

Mass velocity

h

=

Heat transfer coefficient

k

=

Thermal Conductivity

mu

=

Viscosity

rho

=

Density

V

=

Velocity
