Larger head loss coefficients are associated with increased flow contraction in the inlet zone. Culverts having a width less than the upstream channel will constrict flow and can create a steep drop in the water surface profile at the inlet, often resulting in a velocity barrier for fish

Equivalent Length of Pipe Calculator

Unitsf and K are unit less.D and L eq have the same units. For instanceIf D is in meters, then L eq is in meters. If D is in inches, then L eq is in inches. If D is in ft, then L eq is in ft..

HDPE Hydraulic Design Flow Design for Polyethylene Pipe

The internal surface of the PE pipe is smoother than that of concrete or clay pipe. For gravity applications, after some algebraic manipulation to the following Chezy Manning equation, it can be demonstrated that the flow capacity of the PE pipe is 44% greater than that of concrete or clay pipe, considering the internal diameter of the old clay or concrete pipe equal to that of the replacement [price]Pressure drop in pipe fittings and valves equivalent [hdpe]If the equivalent length is calculated from these K values and from the Moody friction factor for clean commercial steel pipe then the 2" bend has an (L e /D) value of 13.8 and the 20" bend has value of 14.0 a change of just over 1% and a strong recommendation for the equivalent length method.[price]Minor or Dynamic Loss Coefficients for Pipe or Tube System [hdpe]Minor or dynamic pressure loss in pipe or tube system components can be eed as. p minor_loss = f v 2 / 2 (1). where . = minor loss coefficient. p minor_loss = minor pressure loss (Pa (N/m 2), psf (lb/ft 2)). f = density of fluid (kg/m 3, slugs/ft 3). v = flow velocity (m/s, ft/s). minor loss can also be eed as head water column mm H2O or inches H2O
