Both calculators run independently — change the inputs on either side to compare results.

Pipe Pressure Drop Calculator

Compute the friction term f·(L/D)·(v²/2) from the Darcy-Weisbach equation — the specific energy loss per unit mass of fluid flowing through a straight pipe. Multiply by fluid density to get pressure drop in Pa, or divide by g for head loss in metres.
