In physics and engineering, in particular fluid dynamics,
the volumetric flow rate (also known as volume flow rate, rate of fluid flow,
or volume velocity) is the volume of fluid which passes per unit time; usually it is represented by the symbol Q (sometimes V̇).
The SI unit is cubic metres per second (m3/s).
Density is a measure of mass per unit of volume.
The average density of an object equals its total mass divided by its total volume.
An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water).
The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids,
it corresponds to the informal concept of "thickness":
for example, syrup has a higher viscosity than water.
Viscosity can be conceptualized as quantifying the internal frictional force that arises between adjacent layers
of fluid that are in relative motion. For instance, when a fluid is forced through a tube, it flows more quickly near the tube's axis than near its walls. In such a case,
experiments show that some stress (such as a pressure difference between the two ends of the tube) is needed to sustain the flow through the tube. This is because a force is required to overcome the friction between the layers of the fluid which are in relative motion: the strength of this force is proportional to the viscosity.
