Hazen-Williams Equation Pipe Inside Diameter

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

This inside pipe diameter formula is used in Hazen-Williams equations and the coefficient formula.

Hazen-Williams Equation Pipe Inside Diameter formula

\(\large{ d = \left(   \frac {Q} { 0.285 \; C \;  m^{0.54} } \right)       ^{\frac {1}{2.63} }   }\)


\(\large{ d }\) = pipe inside diameter (ID)

\(\large{ Q }\) = flow rate

\(\large{ C }\) = Hazen-Williams Coefficient

\(\large{ m }\) = hydraulic grade line slope
