Hazen-Williams Flow through an Open Channel Equation
Hazen-Williams method is only valid for water flowing at ambient temperatures, the Darcy-Weisbach method should be used for other liquids or gases. The Hazen-Williams Equation can be used for flow through an open channel or through a pressurized pipe.

\( k \) = conversion factor | \(dimensionless \) | |
\( C \) = Hazen-Williams coefficient | \( dimensionless \) | |
\( m \) = hydraulic grade line slope | \( ft \) | \(m \) |
\( r_h \) = hydraulic radius | \( ft \) | \( m \) |
