sci.diffusion Calculator
Calculates diffusion distance and flux using Fick's first and second laws from diffusivity, concentration gradient, and time. Einstein's diffusion relation: mean displacement ⟨x²⟩ = 2Dt — a protein with D = 10⁻¹¹ m²/s diffuses ~1 µm in 50 ms in water.
Inputs
D
Reference formula or conversion factor shown for context.
Time
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
C0
Amount of solute per unit volume. Higher concentration = more solute dissolved.
Distance
Separation between two points or total path length. Check that units are consistent throughout the calculation.
Results
C(x,t) est. (mol/m^3)
Reference formula or conversion factor shown for context.
RMS diffusion distance (m)
The computed distance or separation.
characteristic time (s)
The computed duration or time value.
D (m^2/s)
Reference formula or conversion factor shown for context.
