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. The flow rate calculator can also calculate the mass flow rate of a fluid given its density is known. Mehr anzeigen This pipe flow rate calculator calculates the volumetric flow rate (discharge rate) a gas or fluid (liquid) going through a round or rectangular pipe of known dimensions. If the substance is a liquid and its volumetric … Mehr anzeigen There are two main approaches to calculating the flow rate Q which is equivalent to the difference in volume divided by the difference in time (Δv / Δt). The first one is if we know the pressure difference … Mehr anzeigen Example 1: A round pipe has a diameter of 25 mm and water is running through it with a velocity of 10 m/s. What is the flow rate of the water? First, we calculate the cross-section area to be (25/2)^2 · 3.1416 ~= 490.875 … Mehr anzeigen Web1. Introduction Why is the fluid velocity in pipes important ? The fluid velocity in a pipe is a fundamental data to calculate to be able to characterize the flow in a pipe, thanks to the …
