Stanton Number

Stanton Number

Stanton number ( \(St\) ) (dimensionless number) calculates the heat transfer into a fluid to the thermal capacity of fluid.

Stanton Number formula

\(\large{ St = \frac { h  } {C_p \rho v} }\)         

\(\large{ St = \frac { h  } {C_p G} }\)         

Where:

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

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

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

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

\(\large{ v }\) = velocity

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