Volume Flow Rate And Equation Of Continuity Fluids Physics The average resting human heart pumps roughly 330 ml of blood every 4 seconds. so the volume flow rate can be found with. q = v t = 330 ml 4 s = 83 ml s = 0.083 l s . we can convert this to conventional s.i. units of meters cubed per second, m 3 s , by converting liters to meters cubed as follows: q = 0.083 l s × ( 1 m 3 1, 000 l) = 0. Explore the concept of volume flow rate and the equation of continuity for fluids in motion. watch a video lesson with examples and exercises on khan academy. This implies that for incompressible fluid flow, the flow rate av a v must be constant: av = constant. (52.2.1) (52.2.1) a v = constant. the flow rate av a v has units of volume per unit time ( m3 s m 3 s ). this relation is called the continuity equation. you may be familiar with this idea in playing with a garden hose with the nozzle removed. Let's solve a couple of questions on the continuity equationpractice this concept khanacademy.org science in in class11th physics in in class11.

Continuity equation. the continuity equation works under the assumption that the flow of a fluid in will equal the flow out (q1 = q2). the flow rate of a fluid is the volume of fluid which passes through a surface in a given unit of time. it is usually represented by the symbol q. volumetric flow rate is defined as q = va, where q is the flow. We know that those are the going to be the same numbers, because of the equation of continuity. we know that the flow, which is r, which is volume per amount of time, is the same thing as the input velocity times the input area. the input area is 2, so it's 2v1, and that also equals the output area times output velocity, so it equals 1 2 v2.
