What is meant by volumetric flow rate?


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).

What is circular orifice?


Orifices are used as an emptying device for tanks. The classical discharge equation for circular orifice flow from a side of a large tank is where Q is the discharge, C d the discharge coefficient, d the orifice diameter, g the gravitational acceleration and h the depth of orifice centre below free surface.
