Diffusion Coefficient Calculator
Result
Diffusion Coefficient Calculator Estimate the diffusion coefficient of a spherical molecule in solution using the Stokes-Einstein equation. — free online calculator.
Formula
- Diffusion Coefficient Calculator calculates its result from K B, Time, Rate (decimal), Eta. It uses the formula D = k_B × T / (6π × η × r). Change any input to recalculate the result instantly.
- The main inputs are Temperature, Solvent Viscosity, Hydrodynamic Radius. Enter them in the units and format shown in the calculator.
- Use the units, labels and assumptions shown beside each input so the formula is applied consistently.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Diffusion Coefficient
- Temperature: 25
- Solvent Viscosity: 0.89
- Hydrodynamic Radius: 1
Using K B = 2, Time = 3, Rate (decimal) = 0.05, Eta = 5, the calculated result is 1.2732395447.
