Variables Used
Head Loss due to Friction - (Measured in Meter) - The Head Loss due to Friction refers to the loss of energy (or pressure) that occurs when a fluid flows through a pipe or duct due to the resistance created by the surface of the pipe.
Darcy Friction Factor - The Darcy Friction Factor refers to the dimensionless quantity used in fluid mechanics to describe the frictional losses in pipe flow and open-channel flow.
Length of Pipe - (Measured in Meter) - The Length of Pipe refers to total length from one end to another in which the liquid is flowing.
Mean Velocity - (Measured in Meter per Second) - The Mean Velocity refers to the average speed at which fluid flows through a given cross-sectional area of a pipe or channel.
Diameter of Pipe - (Measured in Meter) - The Diameter of Pipe refers to the diameter of the pipe in which the liquid is flowing.
STEP 1: Convert Input(s) to Base Unit
Darcy Friction Factor: 5 --> No Conversion Required
Length of Pipe: 0.1 Meter --> 0.1 Meter No Conversion Required

What is Frictional Resistance ?

Frictional resistance refers to the force that opposes the motion of a fluid or an object as it moves through a medium or along a surface. In the context of fluid dynamics, frictional resistance occurs when a fluid (like water, air, or oil) flows through a pipe, conduit, or any channel, and its interaction with the surface of the material creates resistance, resulting in energy loss.

How to Calculate Head Loss due to Frictional Resistance?

Head Loss due to Frictional Resistance calculator uses Head Loss due to Friction = Darcy Friction Factor*Length of Pipe*(Mean Velocity^2)/(2*[g]*Diameter of Pipe) to calculate the Head Loss due to Friction, The Head Loss due to Frictional Resistance formula is defined as amount of energy lost in terms of height of water in flow. Head Loss due to Friction is denoted by h symbol.
