Overview

Engineering reference data for Pe Pipe Weights 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.

Polyethylene (PE) pipes are manufactured in various pressure grades, designated as PN (Pressure Nominal). The PN rating indicates the maximum continuous operating pressure (in bar) the pipe can safely handle with water at 20 °C.

*PN 2.5: Maximum pressure 2.5 bar
*PN 4: Maximum pressure 4 bar
*PN 6: Maximum pressure 6 bar
*PN 10: Maximum pressure 10 bar
*PN 16: Maximum pressure 16 bar

Pressure Unit Conversions

The reference pressure of 1 bar is equivalent to:

1 \text{ bar} = 10^5 \text{ Pa} = 0.1 \text{ N/mm}^2 = 10.197 \text{ kp/m}^2 = 10.20 \text{ m H}_2\text{O} = 0.9869 \text{ atm} = 14.50 \text{ psi} = 10^6 \text{ dyn/cm}^2 = 750 \text{ mmHg}
