The image above represents friction factor. To calculate friction factor, five essential parameters are needed and these parameters are Diameter of Pipe (D), Change in Pressure (ΔP), Length of Pipe (L), Density of Fluid (ρ) and Velocity of Fluid (v’).
The formula for calculating friction factor:
f = DΔP / 2Lρv’²
Where:
f = Friction Factor
D = Diameter of Pipe
ΔP = Change in Pressure
L = Length of Pipe
ρ = Density of Fluid
v’ = Velocity of Fluid
Let’s solve an example;
Find the friction factor when the diameter of pipe is 4, the change in pressure is 8, the length of pipe is 2, the density of fluid is 5 and the velocity of fluid is 3.
This implies that;
D = Diameter of Pipe = 4
ΔP = Change in Pressure = 8
L = Length of Pipe = 2
ρ = Density of Fluid = 5
v’ = Velocity of Fluid = 3
f = DΔP / 2Lρv’²
f = (4)(8) / 2(2)(5)(3)²
That is, f = 32 / 2(2)(5)(9)
f = 32 / 180
f = 0.177
Therefore, the friction factor is 0.177.
