# Stanton Number

Stanton number, abbreviated as St, is a dimensionless number that calculates the heat transfer into a fluid to the thermal capacity of fluid.

### Stanton Number formula

(Eq. 1) \(\large{ St = \frac { h } {C \; \rho \; v} }\)

(Eq. 2) \(\large{ St = \frac { h } {C \; G} }\)

Where:

\(\large{ St }\) = Stanton number

\(\large{ \rho }\) (Greek symbol rho) = density

\(\large{ C }\) = heat capacity

\(\large{ h }\) = heat transfer coefficient

\(\large{ G }\) = mass velocity

\(\large{ v }\) = velocity
