What is Potential Head Drop?

The head, pressure, or energy (they are the same) lost by water flowing in a pipe or channel as a result of turbulence caused by the velocity of the flowing water and the roughness of the pipe, channel walls, or fittings. Water flowing in a pipe loses head as a result of friction losses.

How to Calculate Potential Head Drop?

Potential Head Drop calculator uses Head Loss due to Friction = (3*Dynamic Viscosity*Mean Velocity*Length of Pipe)/(Specific Weight of Liquid*Diameter of Section^2) to calculate the Head Loss due to Friction, The Potential Head Drop is defined as the loss of head due to differential pressure loss and viscous flow in the channel. Head Loss due to Friction is denoted by h_L symbol.

How to calculate Potential Head Drop using this online calculator? To use this online calculator for Potential Head Drop, enter Dynamic Viscosity (μ), Mean Velocity (V_mean), Length of Pipe (L), Specific Weight of Liquid (γ_f) & Diameter of Section (d_section) and hit the calculate button. Here is how the Potential Head Drop calculation can be explained with given input values -> 1.87156 = (3*1.02*10*15)/(9810*5^2).

FAQ

What is Potential Head Drop?
