Editing Diffusivity

{{SIA-Conversion-Expand}}
'''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|Kinematic viscosity]], characterising momentum diffusivity
*[[Magnetic diffusivity]]

==Dimensions and units==

Diffusivity has dimensions of length<sup>2</sup> / time, or m<sup>2</sup>/s in [[SI units]] and cm<sup>2</sup>/s in [[CGS units]].
