Liquid phase diffusion coefficient online calculator
App description
Enter the value and click "Calculate" to display the result
Calculation formula:
DAB = liquid phase diffusion coefficient (diffusion coefficient of solution A in solution B)
MB = molecular weight of solution B
Φ = correlation factor of solution B
T = absolute temperature
μ = viscosity of solution B
VA = molar volume of solution A
Diffusion can be defined as the mixing of two or more substances or the net motion of a substance from a high concentration to a low concentration region.
The diffusion coefficient can be defined as the ratio of the proportion of the substance represented by the diffusion through the unit concentration gradient per unit area per unit time.
Usage example
Input data:
Solution B correlation factor: 30
