Friction factor comparision

In this example, calculate the head loss for fluid flow in a pipeline using 1. Colebrook and 2. Swamee-Jain approximation for friction factor and 3. using Hazen-Willaims.

Major Loss Hazen

The Hazen-Williams method is valid for water flowing at ordinary temperatures of 4 to 25 oC through pressurized pipes.

The Darcy-Weisbach method is generally considered more accurate than the Hazen-Williams method. Additionally, the Darcy-Weisbach method is valid for any liquid or gas. Major Loss Darcy-Colbrook Calculator

Major Loss Darcy/Swamee

The Darcy-Weisbach method is generally considered more accurate than the Hazen-Williams method. This calculator uses the Swamee Jain apprximation for the friction factor. Major Loss Darcy-Swamee Calculator
