Dimensionless numbers (or characteristic numbers) have an important role in analyzing the behavior of fluids and their flow as well as in other transport phenomena. [1] They include the Reynolds and the Mach numbers, which describe as ratios the relative magnitude of fluid and physical system characteristics, such as density, viscosity, speed of sound, and flow speed.
A key tool used to determine the stability of a flow is the Reynolds number (Re), first put forward by George Gabriel Stokes at the start of the 1850s. Associated with Osborne Reynolds who further developed the idea in the early 1880s, this dimensionless number gives the ratio of inertial terms and viscous terms. [4]
A number of prokaryotic K Ca channels have been described, both structurally and functionally. All are either gated by calcium or other ligands and are homologous to the human K Ca channels, in particular the K Ca 1.1 gating ring. These structures have served as templates for ligand gating.

u is the flow velocity; κ is the thermal conductivity; T 0 is the bulk fluid temperature; T w is the wall temperature; Pr is the Prandtl number; Ec is the Eckert number [1] It is the ratio between heat produced by viscous dissipation and heat transported by molecular conduction. i.e., the ratio of viscous heat generation to external heating.
Salter’s numbers weren’t nearly as good, either. He was 147-of-261 passing for 1,886 yards and 15 TDs to go along with six interceptions. He also rushed for 579 yards and seven scores.
