## Darcy-Weisbach Equation for Calculating Pressure Losses

The Darcy-Weisbach equation is used to calculate the major pressure loss or head loss in a pipe, duct, or tube as a function of the pipe’s length and diameter, the fluid’s density and mean velocity, and an empirical value called the Darcy friction factor. The equation is valid for both laminar flow and turbulent flow. …

## Section Modulus: Calculators and Complete Guide

Section modulus is a geometric property of a cross section used in the design of beams or other flexural members that will experience deflection due to an applied bending moment. The units of section modulus are length^3. There are two types of section moduli: elastic section modulus and plastic section modulus. Elastic section modulus applies …

## Colebrook-White Equation

The Colebrook-White Equation (or simply Colebrook Equation) is an engineering equation used to approximate the Darcy friction factor (or Darcy-Weisbach friction factor) for turbulent flow in full flowing pipes or ducts. The friction factor is required to calculate the pressure drop or head loss due to wall roughness using the Darcy Weisbach equation. where f …
