Stantonn.
/ˈstantən/, U.S. /ˈstæn(t)ən/ Stanton number n. a dimensionless measure of heat transfer used in forced convection studies, equivalent to the ratio of the Nusselt number to the product of the Reynolds and Prandtl numbers, viz. h/cpρv, where h is the heat transfer coefficient of the fluid, cp is its heat capacity at constant pressure, ρ is its density, and v is its velocity. Defined as the reciprocal of the Prandtl number in some dictionaries, but no textual evidence for this has been found.
