How to Calculate and Solve for Kinetic Force of Fluid Flow | Transport Phenomena
Last Updated on October 2, 2021
The image above represents kinetic force of fluid flow.
To compute for kinetic force of fluid flow, three essential parameters are needed and these parameters are Radius of Tube (R), Length of Tube (L) and Shear Stress at Wall (τo).
The formula for calculating kinetic force of fluid flow:
Fk = 2π.RLτo
Where:
Fk = Kinetic Force of Fluid Flow
R = Radius of Tube
L = Length of Tube
τo = Shear Stress at Wall
Let’s solve an example;
Find the kinetic force of fluid flow when the radius of tube is 10, the length of tube is 8 and the shear stress at wall is 4.
This implies that;
R = Radius of Tube = 10
L = Length of Tube = 8
τo = Shear Stress at Wall = 4
Fk = 2π.RLτo
Fk = 2π.(10)(8)(4)
Fk = (6.28).(320)
Fk = 2010.61
Therefore, the kinetic force of fluid flow is 2010.61 N.
Calculating the Radius of Tube when the Kinetic Force of Fluid Flow, the Length of Tube and the Shear Stress at Wall is Given.
R = Fk / 2π.Lτo
Where:
R = Radius of Tube
Fk = Kinetic Force of Fluid Flow
L = Length of Tube
τo = Shear Stress at Wall
Let’s solve an example;
Find the radius of tube when the kinetic force of fluid flow is 24, the length of tube is 2 and the shear stress at wall is 4.
This implies that;
Fk = Kinetic Force of Fluid Flow = 24
L = Length of Tube = 2
τo = Shear Stress at Wall = 4
R = Fk / 2π.Lτo
R = 24 / 2π.(2)(4)
R = 24 / 50.27
R = 0.48
Therefore, the radius of tube is 0.48.
Calculating the Length of Tube when the Kinetic Force of Fluid Flow, the Radius of Tube and the Shear Stress at Wall is Given.
L = Fk / 2π.Rτo
Where:
L = Length of Tube
Fk = Kinetic Force of Fluid Flow
R = Radius of Tube
τo = Shear Stress at Wall
Let’s solve an example;
Find the length of tube when the kinetic force of fluid flow is 42, the radius of the tube is 8 and the shear stress at wall is 5.
This implies that;
Fk = Kinetic Force of Fluid Flow = 42
R = Radius of Tube = 8
τo = Shear Stress at Wall = 5
L = Fk / 2π.Rτo
L = 42 / 2π.(8)(5)
L = 42 / 251.3
L = 0.167
Therefore, the length of tube is 0.167.
Calculating the Shear Stress at Wall when the Kinetic Force of Fluid Flow, the Radius of Tube and the Length of Tube is Given.
τo = Fk / 2π.RL
Where:
τo = Shear Stress at Wall
Fk = Kinetic Force of Fluid Flow
R = Radius of Tube
L = Length of Tube
Let’s solve an example;
Find the shear stress at wall when the kinetic force of fluid flow is 50, the radius of tube is 4 and the length of tube is 2.
This implies that;
Fk = Kinetic Force of Fluid Flow = 50
R = Radius of Tube = 4
L = Length of Tube = 2
τo = Fk / 2π.RL
τo = 50 / 2π.(4)(2)
τo = 50 / 50.27
τo = 0.99
Therefore, the shear stress at wall is 0.99.
