This formula uses 5 Variables

Variables Used

Nusselt Number - The Nusselt Number is the ratio of convective to conductive heat transfer at a boundary in a fluid. Convection includes both advection and diffusion.
Diameter - (Measured in Meter) - Diameter is a straight line passing from side to side through the center of a body or figure, especially a circle or sphere.
Length - (Measured in Meter) - Length is the measurement or extent of something from end to end.
Reynolds Number Dia - Reynolds Number Dia is the ratio of inertial forces to viscous forces.
Prandtl Number - The Prandtl number (Pr) or Prandtl group is a dimensionless number, named after the German physicist Ludwig Prandtl, defined as the ratio of momentum diffusivity to thermal diffusivity.

STEP 1: Convert Input(s) to Base Unit

Diameter: 10 Meter --> 10 Meter No Conversion Required
Length: 3 Meter --> 3 Meter No Conversion Required
Reynolds Number Dia: 1600 --> No Conversion Required
Prandtl Number: 0.7 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Nu = 3.66+((0.0668*(D/L)*Re_D*Pr)/(1+0.04*((D/L)*Re_D*Pr)^0.67)) --> 3.66+((0.0668*(10/3)*1600*0.7)/(1+0.04*((10/3)*1600*0.7)^0.67))

Evaluating ... ...

Nu = 26.5524508136942

STEP 3: Convert Result to Output's Unit

26.5524508136942 --> No Conversion Required

FINAL ANSWER

26.5524508136942 ≈ 26.55245 <-- Nusselt Number

What is internal flow

internal flow is a flow for which the fluid is confined by a surface. Hence the boundary layer is unable to develop without eventually being constrained. The internal flow configuration represents a convenient geometry for heating and cooling fluids used in chemical processing, environmental control, and energy conversion technologies.

An example includes flow in a pipe.
