Friction and Minor Loss Methods Chezy's EquationChezy's equation is rarely used directly, but it is the basis for several other methods, including Manning's equation. Chezy's equation is:

Colebrook-White Equation

The Colebrook-White equation is used to iteratively calculate for the Darcy-Weisbach friction factor:

Hazen-Williams Equation

The Hazen-Williams Formula is frequently used in the analysis of pressure pipe systems (such as water distribution networks and sewer force mains). The formula is as follows:

Darcy-Weisbach Equation

Because of non-empirical origins, the DarcyWeisbach equation is viewed by many engineers as the most accurate method for modeling friction losses. It most commonly takes the following form:

The Kinematic Viscosity is used in determining the friction coefficient in the DarcyWeisbach Friction Method. The default units are initially set by Bentley Systems.

Note:

Manning's roughness coefficients are the same as the roughness coefficients used in Kutter's equation.

Manning's Equation Manning's equation, which is based on Chezy's equation, is one of the most popular methods in use today for free surface flow. For Manning's equation, the roughness coefficient in Chezy's equation is calculated as:

Minor Losses

Minor losses in pressure pipes are caused by localized areas of increased turbulence that create a drop in the energy and hydraulic grades at that point in the system. The magnitude of these losses is dependent primarily upon the shape of the fitting, which directly affects the flow lines in the pipe.

Typical values for fitting loss coefficients are included in the Fittings Table. Generally speaking, more gradual transitions create smoother flow lines and smaller headlosses. For example, the figure below shows the effects of entrance configuration on typical pipe entrance flow lines.
