The image above represents drag force. To calculate drag force, five essential parameters are needed and these parameters are Density (ρ), Viscosity (η), Length of Tube (L), Width of Tube (W) and Velocity at Infinite Flow (v∞).
The formula for calculating drag force:
Fk = 0.664√(ρηLW²v∞³)
Where:
Fk = Drag Force
ρ = Density
η = Viscosity
L = Length of Tube
W = Width of Tube
v∞ = Velocity at Infinite Flow
Let’s solve an example;
If density is 10, the viscosity is 12, the length of tube is 16, the width of tube is 14 and the velocity at infinite flow is 11. Find the drag force?
This implies that;
ρ = Density = 10
η = Viscosity = 12
L = Length of Tube = 16
W = Width of Tube = 14
v∞ = Velocity at Infinite Flow = 11
Fk = 0.664√(ρηLW²v∞³)
That is, Fk = 0.664√((10)(12)(16)(14)²(11)³)
Fk = 0.664√((10)(12)(16)(196)(1331))
Fk = 0.664√(500881920)
So, Fk = 0.664 (22380.39)
Fk = 14860.57
Therefore, the drag force is 14860.57 N.
