ISO 4437 Pe Pipes Gaseous Supply

Overview

Engineering reference data for ISO 4437 Pe Pipes Gaseous Supply in fluid mechanics.

Key Formulas

Reynolds Number

$Re = \frac{\rho v D}{\mu}$

Ratio of inertial to viscous forces — determines flow regime.

Bernoulli's Equation

$P + \frac{1}{2}\rho v^2 + \rho g h = \text{const}$

Conservation of energy for steady, inviscid, incompressible flow.

Continuity Equation

$A_1 v_1 = A_2 v_2$

Conservation of mass for incompressible flow.

Darcy-Weisbach

$\Delta P = f \frac{L}{D} \frac{\rho v^2}{2}$

Pressure drop due to friction in a pipe.

Variables

Pipe Dimensions Data

The following table provides the outer diameter (OD) nominal sizes and corresponding wall thicknesses for PE pipes used in gaseous fuel supply systems, as specified in ISO 4437. The data is presented for two Standard Dimension Ratios: SDR 17 and SDR 11.
