Difference between prandtl number and Schmidt number?

Question

Accepted Answer

Prandtl number and Schmidt number are dimensionless numbers used in fluid mechanics.

Prandtl number represents the ratio of momentum diffusivity to thermal diffusivity in a fluid.
Schmidt number represents the ratio of momentum diffusivity to mass diffusivity in a fluid.
Prandtl number is used to characterize the relative importance of heat transfer and momentum transfer in a fluid.
Schmidt number is used to characterize the relative importance of momentum transfer and mass transfer in a fluid.
Both numbers are important in understanding the behavior of fluids in various applications.

Accepted Answer

Prandtl number is the ratio of momentum diffusivity to thermal diffusivity while Schmidt number is the ratio of momentum diffusivity to mass diffusivity.
