WebCalculation of the Reynolds number. To calculate the Reynolds number, we have to know: the outer diameter of the cladding is: d = 2 x r Zr,1 = 9,3 mm (to calculate the hydraulic diameter) the pitch of fuel pins is: p = 13 mm (to calculate the hydraulic diameter) the dynamic viscosity of saturated water at 300°C is: μ = 0.0000859 N.s/m 2 WebGrashof Number Calculator. G r = g β ( T s − T ∞) L 3 ν 2. Gravitational Acceleration ( g ): Coefficient of Thermal Expansion ( β ): Surface Temperature ( T s ): Bulk Fluid Temperature ( T inf ): Vertical Length ( L ): WebRayleigh number is defined as the product of grashof number and Prandtl number. The rayleigh number is denoted by the symbol Ra. As per the definition of rayleigh number, Ra = Gr × Pr. Where equation for the grashof number is, Gr = ρ2gL3βΔT μ2 G r = ρ 2 g L 3 β Δ T μ 2.
