Darcy friction factor for Colburn analogy Solution

STEP 0: Pre-Calculation Summary
Formula Used
Darcy Friction Factor = 8*Stanton Number*Prandtl Number^0.67
df = 8*St*Pr^0.67
This formula uses 3 Variables
Variables Used
Darcy Friction Factor - Darcy Friction Factor is denoted by f. Its value depends on the flow's Reynolds number Re and on the pipe's relative roughness ε / D. It can be obtained from Moody's chart.
Stanton Number - The Stanton Number is a dimensionless number that measures the ratio of heat transferred into a fluid to the thermal capacity of the fluid.
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
Stanton Number: 0.4 --> No Conversion Required
Prandtl Number: 0.7 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
df = 8*St*Pr^0.67 --> 8*0.4*0.7^0.67
Evaluating ... ...
df = 2.51979764165058

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.
