Easy
In forced convective heat transfer, Stanton number (St), Nusselt number (Nu), Reynolds number (Re) and Prandtl number (Pr) are related as
- St = Nu/(Re Pr)
- BSt = Nu Pr/Re
- CSt = Nu Pr Re
- DSt = Nu Re/Pr
Explanation
By definition, St = Nu/(Re·Pr) — a standard dimensionless-group identity relating heat-transfer coefficient, Reynolds number, and Prandtl number in forced convection.
