WebGrashof number replaces the Reynolds number in the convection correlation equation. In free convection, buoyancy driven flow sometimes dominates the flow inertia, therefore, the Nusselt number is a function of the Grashof number and the Prandtle number alone. Nu=f(Gr, Pr). Reynolds number will be important if there is an external flow. WebThe Grashof Number formula for pipes is: GrD = g⋅ β(T s − T ∞)L3 ν2 G r D = g · β ( T s - T ∞) L 3 ν 2, where: Gr D is the Grashof Number for Vertical Flat Plates. g is the gravitational acceleration. β is coefficient of thermal expansion in (1/K) T s is the surface temperature. T ∞ is the bulk temperature.
