How to Calculate and Solve for Specific Permeability | Transport Phenomena
Last Updated on October 2, 2021
The image above represents specific permeability.
To compute for specific permeability, two essential parameters are needed and these parameters are Geometry Specification (P) and Viscosity of Fluid (η).
The formula for calculating specific permeability:
K’D = P / η
Where:
K’D = Specific Permeability
P = Geometry Specification
η = Viscosity of Fluid
Let’s solve an example;
Find the specific permeability when the geometry specification is 10 and the viscosity of fluid is 2.
This implies that;
P = Geometry Specification = 10
η = Viscosity of Fluid = 2
K’D = P / η
K’D = 10 / 2
K’D = 5
Therefore, the specific permeability is 5 N/A².
Calculating the Geometry Specification when the Specific Permeability and the Viscosity of Fluid is Given.
P = K’D x η
Where:
P = Geometry Specification
K’D = Specific Permeability
η = Viscosity of Fluid
Let’s solve an example;
Given that the specific permeability is 10 and the viscosity of fluid is 3. Find the geometry specification?
This implies that;
K’D = Specific Permeability = 10
η = Viscosity of Fluid = 3
P = K’D x η
P = 10 x 3
P = 30
Therefore, the geometry specification is 30.
Calculating the Viscosity of Fluid when the Specific Permeability and the Geometry Specification is Given.
η = P / K’D
Where:
η = Viscosity of Fluid
K’D = Specific Permeability
P = Geometry Specification
Let’s solve an example;
Find the viscosity of fluid when the specific permeability is 20 and the geometry specification is 60.
This implies that;
K’D = Specific Permeability = 20
P = Geometry Specification = 60
η = P / K’D
η = 60 / 20
η = 3
Therefore, the viscosity of fluid is 3.
