## Colburn Factor using Chilton Colburn Analogy Solution

STEP 0: Pre-Calculation Summary
Formula Used
Colburn's j-factor = Nusselt Number/(Reynolds Number)*(Prandtl Number)^(1/3)
jH = Nu/(Re)*(Pr)^(1/3)
This formula uses 3 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.
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
