# Piping – Moody Friction Factor

The factor of proportionality in the previous equations is called the  Moody friction factor and is determined from the Moody resistance diagram shown in Figure…

# Piping – Darcy's Equation

This equation, which is also sometimes called the Weisbach equation or the Darcy-Weisbach equation, states that the friction head loss between two points in a…

# Piping – Bernoulli's Theorem

It is customary to express the energy contained in a fluid in terms of the potential energy contained in an equivalent height or “head” of…

# Piping – Flow Regimes

Flow regimes describe the nature of fluid flow. There are two basic flow regimes for flow of a single-phase fluid: laminar flow and turbulent flow.…

# Piping – Reynolds Number

The Reynolds number is a dimensionless parameter that relates the ratio of inertial forces to viscous forces. It can be expressed by the following general…

# Pressure Drop In Piping

Piping design in production facilities involves the selection of a pipe diameter and a wall thickness that is capable of transporting fluid from one piece…
