The Hazen-Williams method is valid for water flowing at ordinary temperatures of 40 to 75 oF (4 to 25 oC) velocity or pipe diameter. Enter 9 in the in the flow rate box and choose liters per second from its menu.
k=1.318 for English units (feet and seconds).

Pressure drop by Hazen-Williams equation. D=Pipe inside diameter. Hazen-Williams method. Hazen-Williams friction loss calculator Enter 10 in the pipe diameter box and choose centimeters from its menu. To estimate pipe volume, use the following formula: volume = π × d 2 4 × h. Thus, the volume of a pipe is equal to pi times the pipe diameter d squared over 4, times the length of the pipe h.

This flow calculator allows the user to easily determine critical flow properties (flow rate, velocity, friction loss, etc.) Pipe Flow Calculators.

Convenient (metric, imperial, US) units may be …

You can view and modify all these parameters (area, perimeter, hydraulic radius) in the advanced mode of this pipe flow calculator. The volume of fluid in a pipe can be found given the inner diameter of the pipe and the length. To calculate internal pipe diameter, you should only enter flow rate and velocity in corresponding fields in the calculator and click calculate button to get results.

Hazen-Williams Coefficient (C) varies from approximately C=60 for 40-year old cast iron pipe to C=150 for calculations where you are solving for flowrate (discharge), velocity, or diameter. Celebrating 20 years This website is offering pipe flow calculators for everyday problem-solving in the field of fluid dynamics. The Hazen-Williams equation is typically used to analyze city water supply systems. (expressed in length units - think of it as energy per unit weight of fluid) due to Hazen-Williams friction loss calculator for water flow in pipes : Solve for: Discharge, Q (ft 3 /s): ... Hazen-Williams Coefficient (C) varies from approximately C=60 for 40-year old cast iron pipe to C=150 for new plastic pipe.   where   S = hf / L  and   Q = V π D2 / 4. k is a unit conversion factor: The higher the C, the smoother the pipe. Result will be displayed. If the substance is a liquid and its volumetric density is known the calculator will also output the mass flow rate (more information is required to calculate it for gases and it is currently not supported). through pressurized pipes. The higher the C, the smoother the pipe. © 1998-2014 LMNO Engineering, Research, and
