CHEMISTRY GLOSSARY

Reynolds number    →   Reynoldsova značajka

Reynolds number (Re) is a dimensionless quantity used in fluid mechanics, defined by

where ρ is density, v is velocity, l is length, and η is viscosity.

Schmidt number    →   Schmidtova značajka

Schmidt number (Sc) is a dimensionless quantity used in fluid mechanics, defined by

where η is viscosity, ρ is density, and D is diffusion coefficient.

laminar flow    →   laminarno strujanje

Laminar flow is a smooth, uniform, non-turbulent flow of a gas or liquid in parallel layers, with little mixing between layers. It is characterised by small values of the Reynolds number.
