## Nusselt Number Using Dittus Boelter Equation for Heating Solution

STEP 0: Pre-Calculation Summary
Formula Used
Nusselt Number = 0.023*(Reynolds Number)^0.8*(Prandtl Number)^0.4
Nu = 0.023*(Re)^0.8*(Pr)^0.4
This formula uses 2 Variables
Variables Used
Reynolds Number- The Reynolds number is the ratio of inertial forces to viscous forces within a fluid which is subjected to relative internal movement due to different fluid velocities. A region where these forces change behavior is known as a boundary layer, such as the bounding surface in the interior of a pipe.
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
