WebCarathéodory. In physics and engineering, in particular fluid dynamics, the volumetric flow rate (also known as volume flow rate, or volume velocity) is the volume of fluid which passes per unit time; usually it is represented by the symbol Q (sometimes V̇ ). It contrasts with mass flow rate, which is the other main type of fluid flow rate. WebTo what does the continuity equation reduce in incompressible flow?

WebSince volume flow rate measures the amount of volume that passes through an area per time, the equation for the volume flow rate looks like this: \Large Q=\dfrac {V} {t}=\dfrac {Volume} {time} Q = tV = timeV olume. In S.I. units (International System of Units), volume flow … WebUsing this equation, pressure drop ‘∆p’ in the laminar regime across ‘l’ length of the pipe can be easily calculated. To summarize the laminar flow equation: The flow rate is directly proportional to the radius of the pipe. Thus, the small increase in pipe diameter can significantly increase the flow rate in the system.

WebA A is the cross sectional area of a section of the pipe, and v v is the speed of the fluid in that section.
