WebWe can determine the volumetric flow rate as follows: The flow rate will vary according to the cross-sectional area of the channel: Area = π * (Diameter) 2 / 4. Area = 3.1415926 * … 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 the flow rate is Q = Ad / t = A¯ v.
WebJan 21, 2024 · 1. Consider a pipe with length L and uniform radius A is held vertically. According to the continuity equation, the velocity of water going into the pipe seems to be the same as the velocity of water coming out. But according to Bernoulli's equation: P a t m + 1 2 ρ v 1 2 + ρ g L = P a t m + 1 2 ρ v 2 2. v 2 = v 1 2 + 2 g L. WebAug 15, 2024 · Now as the density of water remains constant throughout, ρ 1 = ρ 2 = ρ. Now, the equation will look like: ρ g h 1 + 1 2 ρ v 1 2 = ρ g h 2 + 1 2 ρ v 2 2. So, you can clearly visualize that if h 1 > h 2 then v 1 must …
