The formula to calculate the Nusselt Number (Nu) is:
Nu=(fDarcy8)⋅(Re−1000)⋅Pr1+12.7⋅((fDarcy8)0.5)⋅(Pr23−1)
The Nusselt Number is the ratio of convective to conductive heat transfer at a boundary in a fluid. Convection includes both advection and diffusion.
Let's assume the following values:
Using the formula:
Nu=(0.048)⋅(5000−1000)⋅0.71+12.7⋅((0.048)0.5)⋅(0.723−1)≈17.2849322852078
The Nusselt Number is approximately 17.2849322852078.
