# Stanton Number

Written by Jerry Ratzlaff on . Posted in Dimensionless Numbers

Stanton Number is a dimensionless number calculates the heat transfer into a fluid to the thermal capacity of fluid.

## formula

$$St = \frac { h } {C_p \rho v}$$

$$St = \frac { h } {C_p G}$$

Where:

$$St$$ = Stanton Number

$$h$$ = heat transfer coefficient

$$C_p$$ = heat capacity

$$\rho$$ = density

$$v$$ = velocity

$$G$$ = mass velocity
