Pipe Pressure Drop Calculator (Darcy-Weisbach And Hazen-Williams)
Pipe Pressure Drop Calculator (Darcy-Weisbach And Hazen-Williams): a planned Super Calculator tool. Covers flow rate, pipe diameter and material and roughness.
Pipe Pressure Drop Calculator (Darcy-Weisbach And Hazen-Williams) is a planned calculator in the engineering section of Super Calculator, covering building services engineering.
What this calculator will compute
Inputs: flow rate, pipe diameter, material and roughness, length, fluid and temperature, fittings and valves, elevation change and method.
Outputs: pressure drop, friction factor, Reynolds number and flow regime, velocity, equivalent length of fittings and required pipe size for a limit.
Formula, recorded as scope and not yet verified against a primary source: Darcy-Weisbach: delta P = f (L/D)(rho v^2/2), with the friction factor from the Colebrook-White equation solved iteratively or the Swamee-Jain explicit approximation. Hazen-Williams is an empirical alternative valid for water near ambient temperature only, using a C factor by pipe material.
