Overview

Engineering reference data for Pe Pipe Dimensions in piping systems.

$A_1 v_1 = A_2 v_2$

Mass conservation in pipe flow.

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

Darcy-Weisbach equation.

$A = \frac{\pi D^2}{4}$

Cross-sectional area of a pipe.

The PN (Pressure Nominal) grade indicates the maximum allowable operating pressure in bars for PE pipes with water at 20°C.
