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.
