hL = (3*μ*Vmean*L)/(γf*dsection^2)
This formula uses 6 Variables
Variables Used
Head Loss due to Friction - (Measured in Meter) - The Head Loss due to Friction refers to the reduction in pressure (or head) that occurs as fluid flows through a pipe or hydraulic system.
Dynamic Viscosity - (Measured in Pascal Second) - The Dynamic Viscosity refers to the internal resistance of a fluid to flow when a force is applied.
Mean Velocity - (Measured in Meter per Second) - The Mean Velocity refers to the average rate at which an object or fluid moves over a given time interval.
Length of Pipe - (Measured in Meter) - The Length of Pipe refers to the measurement of the pipe from one end to the other.
Specific Weight of Liquid - (Measured in Kilonewton per Cubic Meter) - The Specific Weight of Liquid refers to the weight per unit volume of that substance.
Diameter of Section - (Measured in Meter) - The Diameter of Section refers to the length of the segment that passes through the center of the circle and touches two points on the edge of the circle.
STEP 1: Convert Input(s) to Base Unit
Dynamic Viscosity: 10.2 Poise --> 1.02 Pascal Second (Check conversion ​here)
Mean Velocity: 10 Meter per Second --> 10 Meter per Second No Conversion Required
Length of Pipe: 15 Meter --> 15 Meter No Conversion Required
Specific Weight of Liquid: 9.81 Kilonewton per Cubic Meter --> 9.81 Kilonewton per Cubic Meter No Conversion Required

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 hL 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 (Vmean), Length of Pipe (L), Specific Weight of Liquid f) & Diameter of Section (dsection) 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?
The Potential Head Drop is defined as the loss of head due to differential pressure loss and viscous flow in the channel and is represented as hL = (3*μ*Vmean*L)/(γf*dsection^2) or Head Loss due to Friction = (3*Dynamic Viscosity*Mean Velocity*Length of Pipe)/(Specific Weight of Liquid*Diameter of Section^2). The Dynamic Viscosity refers to the internal resistance of a fluid to flow when a force is applied, The Mean Velocity refers to the average rate at which an object or fluid moves over a given time interval, The Length of Pipe refers to the measurement of the pipe from one end to the other, The Specific Weight of Liquid refers to the weight per unit volume of that substance & The Diameter of Section refers to the length of the segment that passes through the center of the circle and touches two points on the edge of the circle.
How to calculate Potential Head Drop?
