Stanton Number Equation and Calculator

The Stanton number is a dimensionless number that measures the ratio of heat transferred into a fluid to the thermal capacity of fluid.

Eq. 1
s_t = h / ( ρ · µ · c_p )

Where:

h = Convective heat transfer coefficient of the fluid (W/(m² K))
ρ = Density of the fluid (kg/m³)
µ = Velocity of the fluid (m/s)
c_p = Specific heat of the fluid (J/kg K)
s_t = Stanton number (dimensionless)
