The permeability coefficient is represented by the image below. To calculate permeability coefficient, two essential parameters are needed and these parameters are Diffusion Coefficient (D) and Solubility of the Polymer (S).
The formula for calculating the permeability coefficient:
Pm = DS
Where;
Pm = Permeability Coefficient
D = Diffusion Coefficient
S = Solubility of the Polymer
Let’s solve an example;
Given that the diffusion coefficient is 24 and the solubility of the polymer is 12. Find the permeability coefficient?
This implies that;
D = Diffusion Coefficient = 24
S = Solubility of the Polymer = 12
Pm = (24)(12)
Pm = 288
Therefore, the permeability coefficient is 288 Kg/msPa.
Calculating the Diffusion Coefficient when the Permeability Coefficient and the Solubility of the Polymer are Given
D = Pm / S
Where;
D = Diffusion Coefficient
Pm = Permeability Coefficient
S = Solubility of the Polymer
Given an example;
Find the diffusion coefficient when the permeability coefficient is 30 and the solubility of the polymer is 5.
This implies that;

Pm = Permeability Coefficient = 30
S = Solubility of the Polymer = 5
D = Pm / S
That is, D = 30 / 5
D = 6
Therefore, the diffusion coefficient is 6.
Calculating the Solubility of the Polymer when the Permeability Coefficient and the Diffusion Coefficient are Given
S = Pm / D
Where;
S = Solubility of the Polymer
Pm = Permeability Coefficient
D = Diffusion Coefficient
Given an example;
Find the solubility of the polymer when the permeability coefficient is 48 and the diffusion coefficient is 8.
This implies that;
Pm = Permeability Coefficient = 48
D = Diffusion Coefficient = 8
S = Pm / D
Then, S = 48 / 8
S = 6
Therefore, the solubility of the polymer is 6.
