Closed Conduit Hydraulics - Darcy-Weisbach Equation
The Darcy-Weisbach equation is used to determine flow characteristics in closed conduit systems (pipes). It is probably more common than the Hazen-Williams equation due to it being able to solve for systems in both laminar AND turbulent flow.
- headloss (ft)
- friction factor , length
- length (ft)
- diameter (ft)
- gravity g
The friction factor is either given or must be calculated using a Moody-Stanton diagram (available in both the AIO and CERM). Getting the friction factor from a Moody-Stanton chart requires the Reynolds Number , and relative roughness . Click here to continue reading
