Determine the (average) velocity of … WebThe Equations. This flow calculator uses the Hazen Williams equation to solve for flow assuming that the pressure at the outlet is zero (open to atmosphere) and thus the entire pressure at the hose bib is dissipated by friction losses in the hose. The pressure at the hose bib is assumed to be the dynamic pressure (while water is flowing) not ...

WebDec 22, 2024 · The flow rate formula, in general, is. Q=Av Q = Av. where Q is the flow rate, A is the cross-sectional area at a point in the path of the flow and v is the velocity of the liquid at that point. In some situations, such as that of water flowing in a riverbed, calculating A is difficult, and the best you can do is an approximation. In others ... WebFlow Rate Formula Questions: 1) Water is flowing through a circular pipe that has a radius of 0.0800 m.The velocity of the water is 3.30 m/s.What is the flow rate of the water in liters per second (L/s)?Answer: The flow rate depends on the area of the circular pipe: A = πr 2. A = π(0.0800 m) 2 A = π(0.00640 m 2). A = 0.0201 m 2. The area of the pipe is 0.0201 m 2.
