Diffusivity \Dif`fu*siv"i*ty\, n. Tendency to become diffused; tendency, as of heat, to become equalized by spreading through a conducting medium.
n. 1 A tendency to diffuse 2 (context physics English) a coefficient of diffusion; especially the amount of heat that passes through a given area in unit time
Diffusivity is a rate of diffusion, a measure of the rate at which particles or heat or fluids can spread.
It is measured differently for different mediums.
Diffusivity may refer to:
- Thermal diffusivity, diffusivity of heat
- Diffusivity of mass:
- Mass diffusivity, molecular diffusivity (often called "diffusion coefficient")
- Eddy diffusion, eddy diffusivity
- Viscosity#Kinematic_viscosity, momentum diffusivity
- Magnetic diffusivity
Usage examples of "diffusivity".
I suspect there are differences in diffusivity rates from ordinary water, and that could have long-term fatal effects, but .
