Flow volume
WebSep 12, 2024 · where V is the volume and t is the elapsed time. In Figure 14.7.3, the volume of the cylinder is Ax, so the flow rate is. Q = dV dt = d dt(Ax) = Adx dt = Av. The … 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. In most contexts a mention of rate of fluid flow is likely to refer to the volumetric r…

WebMar 7, 2024 · The flow volume was then calculated as the product of the flow area multiplied by the average flow thickness. The eruption rate equaled this volume divided by the duration of the eruption in seconds. For the first year of Pu‘u ‘Ō‘ō activity, calculated eruption rates were 15–65 cubic meters (4,000–17,000 gallons) per second.
