Find the permeability if diffusivity is 2 units and solubility coeffic...
Understanding the Relationship between Permeability, Diffusivity, and Solubility
In chemical engineering, the relationship between permeability (k), diffusivity (D), and solubility coefficient (S) can be expressed using the equation:
k = D * S
Where:
- k = permeability
- D = diffusivity
- S = solubility coefficient
Given values:
- Diffusivity (D) = 2 units
- Solubility Coefficient (S) = 5 units
Calculating Permeability
To find the permeability (k), we can substitute the given values into the equation:
k = D * S
k = 2 units * 5 units
k = 10 units
Thus, the calculated permeability is 10 units.
Conclusion
Based on the calculations, the correct answer for the permeability is:
- a) 10 units
This matches the provided option 'A', confirming its correctness.
Summary of Key Points
- Permeability is derived from the product of diffusivity and solubility coefficient.
- The formula k = D * S is essential for this calculation.
- Given values lead to a permeability of 10 units, aligning with option 'A'.
Understanding these relationships is crucial in chemical engineering, particularly in processes involving mass transfer and transport phenomena.
