Where:
﻿﻿Re
 is Reynolds Number (dimensionless), which is the ratio of inertial forces to friction forces in a fluid flow. It's used to determine whether a flow is laminar or turbulent.
﻿﻿Sc
 is Schmidt Number (dimensionless), which is the ratio of two types of diffusion, momentum diffusion and mass diffusion. The Schmidt number is the mass transfer analogue of the Prandtl number. 
﻿﻿Pe
 is Péclet Number (dimensionless), which is the ratio of advection to diffusion in a fluid.
