How to Evaluate Nusselt Number for Turbulent Flow in Smooth Tube?

Nusselt Number for Turbulent Flow in Smooth Tube evaluator uses Nusselt Number = 0.023*(Reynolds Number in Tube^(0.8))*(Prandtl Number^(0.4)) to evaluate the Nusselt Number, The Nusselt Number for Turbulent Flow in Smooth Tube formula is defined as the function of Reynolds Number and Prandtl Number. The Nusselt number may be interpreted as the ratio of heat transfer by convection to conduction across the fluid layer of thickness L. A larger value of the Nusselt number implies enhanced heat transfer by convection. Nusselt number on the other hand is a non-dimensional heat transfer coefficient. It is used to determine whether the heat transfer is conduction or convection. Nusselt Number is denoted by Nu_d symbol.
