Flow Terms Quiz 1

The amount of fluid that passes a specific point of a process line in a specific amount of time. Can be volumetric or mass

The quantity of fluid that passes a point during a specific time interval

The degree of consistency measured by the quantity of mass (Kg) per unit volume (m3)

The ratio of the density of a substance to the density of a standard

A quantity measuring the force needed to overcome internal friction in a fluid. The resistance to flow of a fluid

A measure of the resistance of the flow of a fluid, equal to its absolute viscosity divided by the density

Dimensionless number that gives a measure of the ratio of inertial forces to viscous forces for given flow conditions.

occurs when a fluid flows in parallel layers, with no disruption between the layers

Fluids that can have a change in density. Normally this will be gases. The changes in density can be because of temperature changes or volumetric changes.

flow in which the fluid undergoes irregular fluctuations, or mixing, the speed of the fluid at a point is continuously undergoing changes in both magnitude and direction
