This is the inside diameter of hose. The hose diameters are in 1/16 of a inch increments and correspond to the following dash sizes: -3, -4, -5, -6, -8, -10, -12, -16, -20, -24, -32, -40, -48, -56, & -64.
This is the volume of fluid per unit of time. This program requires the units in gallons per minute (GPM).
The ratio of the fluid's density to water's density at some specified temperature. This is specified by the properties of the fluid being used.
The measurement of a fluid's internal friction or resistance to flow. This program uses centipoises for the units. (This viscosity is the dynamic(absolute) viscosity of the fluid, not the kinematic viscosity.)
Uniform flow of the fluid. The fluid particles flow in parallel layers. (Re £ 2000)
The fluid begins to fluctuate in the transition region between laminar and turbulent flow. (2000 < Re < 3000)Turbulent FlowNon-uniform (turbulent) flow of fluid. The fluid particles no longer flow in parallel layers. (Re ³ 3000)
Used to study the viscous flow of the fluid and to help determine the flow.
The fluid's distance traveled over a unit of time. The units this program uses feet per second. The velocity of the fluid must be kept under 35ft/s and maintain a laminar flow, to keep from tube peeling.
