fluid flow velocity
1Flow velocity — In fluid dynamics the flow velocity, or velocity field, of a fluid is a vector field which is used to mathematically describe the motion of a fluid.DefinitionThe flow velocity of a fluid is a vector field: mathbf{u}=mathbf{u}(mathbf{x},t)which… …
2Flow measurement — is the quantification of bulk fluid movement. Flow can be measured in a variety of ways. Positive displacement flow meters acumulate a fixed volume of fluid and then count the number of times the volume is filled to measure flow. Other flow… …
3fluid mechanics — an applied science dealing with the basic principles of gaseous and liquid matter. Cf. fluid dynamics. [1940 45] * * * Study of the effects of forces and energy on liquids and gases. One branch of the field, hydrostatics, deals with fluids at… …

6Velocity potential — A velocity potential is used in fluid dynamics, when a fluid occupies a simply connected region and is irrotational. In such a case,: abla imes mathbf{u} =0,where mathbf{u} denotes the flow velocity of the fluid. As a result, mathbf{u} can be… …
7Flow visualization — In fluid dynamics it is critically important to see the patterns produced by flowing fluids, in order to understand them. We can appreciate this on several levels: Most fluids (air, water, etc.) are transparent, thus their flow patterns are… …
8Fluid parcel — In fluid dynamics, within the framework of continuum mechanics, a fluid parcel is a very small amount of fluid, identifiable throughout its dynamic history while moving with the fluid flow.[1] As it moves, the mass of a fluid parcel remains… …
9Flow sensor — A flow sensor is a device for sensing the rate of fluid flow. Typically a flow sensor is the sensing element used in a flow meter, or flow logger, to record the flow of fluids.As is true for all sensors, absolute accuracy of a measurement… …
10Flow coefficient — The flow coefficient of a device is a relative measure of its efficiency at allowing fluid flow. It describes the relationship between the pressure drop across an orifice, valve or other assembly and the corresponding flow rate.Coefficent of… …
