The image above represents velocity at turbulent flow.
To compute for velocity at turbulent flow, four essential parameters are needed and these parameters are Acceleration due to Gravity (g), Particle Diameter (d), Density of Solid Particle (ρs) and Density of Fluid (ρf).
The formula for calculating velocity at turbulent flow:
v = [3gd(ρs – ρf)/ρf]0.5
Where:
v = Velocity at Turbulent Flow
g = Acceleration due to Gravity
d = Particle Diameter
ρs = Density of Solid Particle
ρf = Density of Fluid
Let’s solve an example;
Find the velocity at turbulent flow when the acceleration due to gravity is 14, the particle diameter is 10, the density of solid particle is 24 and the density of fluid is 12.
This implies that;
g = Acceleration due to Gravity = 14
d = Particle Diameter = 10
ρs = Density of Solid Particle = 24
ρf = Density of Fluid = 12
v = [3gd(ρs – ρf)/ρf]0.5
v = [3(14)(10)(24 – 12)/12]0.5
v = [3(14)(10)(12)/12]0.5
v = [5040/12]0.5
v = (420)0.5
v = 20.49
Therefore, the velocity at turbulent flow is 20.49 m/s.
