Easily calculate the volumetric flow rate of a pipe (a.k.a. discharge rate) given its dimensions and either a pressure difference between its ends or the velocity of the liquid or gas flowing through it.
This equation shows clearly how flow varies with the pertinent parameters. Obviously bigger, shorter, colder, more efficient pipes containing lighter gasses permit more flow.
Pipe diameter and flow velocity calculation use the continuity equation that gives the relation between flow rate, flow velocity, and interior pipe diameter. For gas flow, the equation for perfect gas is used to calculate density from gas constant, absolute pressure, and temperature.
24 Ιουλ 2024 · Use this pipe flow calculator to analyze the properties of water flowing in a gravity-fed system. You only need to know the diameter of the pipe, the material it's made of, its length, and the drop in height. We then apply the Hazen-Williams equation for you, which calculates the resulting velocity and discharge. Interested?
7 Αυγ 2017 · How to Calculate Flow Rate With Pipe Size and Pressure. A higher pressure drop acting on a pipe creates a higher flow rate. A wider pipe also produces a higher volumetric flow, and a shorter pipe lets a similar pressure drop provide a greater force.
Calculators for pipe diameter, flow rate, pressure drop, orifice plate, Reynolds number, Venturi effect, resistance coefficient and more.
28 Ιουλ 2024 · Volumetric flow rate formula: \dot {V} = A\cdot v V ˙ = A ⋅ v. where: A A — The cross-sectional area; and. v v — The flow velocity. Mass flow rate formula: \dot {m} = \rho\cdot\dot {V} =\rho\cdot A\cdot v m˙ = ρ ⋅ V ˙ = ρ ⋅ A ⋅ v. where ρ ρ is the fluid's density.
