Pressure Drop

Written by Matt Milbury on . Posted in Pump

presser dropThe difference in pressure between two points, usually caused by friction resistance in the pipe, but moisture can also affect it.

Pressure Drop Formula

\(\large{ \Delta p = \frac{f \; l \; v^2}{2 \; g \; d}  }\)         


\(\large{ J }\) = pressure drop

\(\large{ \mathrm {f} }\) = friction factor

\(\large{ g }\) = gravirational acceleration

\(\large{ d }\) = inside diameter of pipe

\(\large{ l }\) = lenght of pipe

\(\large{ v }\) = velocity of the fluid
