WebFeb 20, 2024 · Figure 12.1.1: Flow rate is the volume of fluid per unit time flowing past a point through the area A. re the shaded cylinder of fluid flows past point P in a uniform pipe in time t. The volume of the cylinder is Ad and the average velocity is ¯ v = d / t so that … WebThe greater the velocity of the water, the greater the flow rate of the river. But flow rate also depends on the size of the river. A rapid mountain stream carries far less water than the Amazon River in Brazil, for example. The precise relationship between flow rate Q Q size 12{Q} {} and velocity v ¯ v ¯ size 12{ {overline {v}} } {} is

WebThe flow rate is the average velocity times the area. If the velocity was constant, you would get a flow rate that scaled with r 2 (the area). But the velocity goes up for larger pipes - in fact, velocity scales with the square of the radius. And the product of these two squares gives us the 4th power relationship.

WebFlow rate Q is defined to be the volume of fluid passing by some location through an area during a period of time, as seen in Figure 12.2. In symbols, this can be written as. 12.1 Q = V t, where V is the volume and t is the elapsed time.
