# Friction Loss Calculator

The friction loss calculator can help you calculate the amount of pressure head loss due to friction for a given pipe dimension and volumetric flow rate. Friction affects fluid movement inside a pipe or conduit, just as it does when push a heavy box through a rough surface.

Friction Loss Calculator: The purpose of this Friction Loss Calculator also known as a Line Loss Calculator, is to determine the pressure drop produced by friction in a pipeline. It's not meant to be used for complicated friction loss calculations rather, it is meant to provide a quick, reasonably accurate estimate of friction loss in simple piping systems.

It might be difficult to calculate friction loss in a pipe system. This line loss / friction loss calculator is designed to serve as a starting point for calculating friction losses in simple piping systems. For assistance with friction loss estimates or the design of a complete packaged pumping system with pipework.

## What is Friction Loss? | Friction Loss in Pipe Formula

When a fluid flows through a conduit or pipe, the roughness of the internal pipe walls and the viscosity of the fluid effect the fluid flow, resulting in energy or pressure loss. This pressure loss has an impact on pumping machine efficiency as well as output at the outlet. The friction loss formula is Hl = f*L/D*v2/2g

• f be the friction factor
• L be the length of the pipe
• D denotes the inner diameter of the pipe
• V be the velocity of the liquid
• g be the gravitational constant
• hl is the friction lost

### How do you Calculate Friction Loss in a Pipe?

The friction loss may be estimated in five simple steps:

• Choose the pipes material or manually input the Hazen Williams Coefficient.
• Enter the pipe's internal diameter.
• Put in the length of your pipe here.
• Enter the flowrate of your pipe.
• You will get a result for the pipes friction loss if you click the calculate button.

### Friction Loss Examples

Question 1: Find out the friction loss, if the inner diameter and length of the pipe are 0.3 m and 30 m respectively. Also, the friction factor and velocity of the liquid are 0.4 and 25 m per sec?

Solution:

Consider the problem,

• Length of the pipe, L = 30 m
• Internal diameter, D = 0.3 m
• Velocity of the liquid, v = 25 m per sec
• friction factor, f = 0.4
• g = 9.8 mper.sqsec2

The friction loss formula is Hl=f*L/D*v2/2g.

Hl = 0.4*300.3*2522*9.8

Hl = 1275.51m

Therefore, the friction loss is 1275.51m

### FAQs on Friction Loss Calculator

1. What is the definition of pump friction loss?

Friction loss is the energy or "head" lost in pipe flow as a result of viscous effects caused by the pipes surface.

2. What is pipe friction loss?

Friction loss is the amount of energy lost by your piping system as a result of fluids encountering resistance.

3. Is a loss of head the same as a loss of friction?

The reduction in the total head (sum of elevation head, velocity head, and pressure head) of the fluid as it passes through a fluid system is referred to as head loss.
