Flow Rate Calculator - Calculate the flow rate of a pipe

Calculation examples. 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 mm 2 via the area of a circle formula.We can convert this to m 2 by dividing by 1,000,000 for more convenient results, getting 0.000490875 m 2.

LDH Supply Hose - Large Diameter - Rawhide Fire Hose

LDH fire hose is big-flow, low-pressure hose, which is both its defining feature and the reason for its popularity. Friction loss in large diameter fire hoses is entirely dependent upon flow, not pressure, so the more capacity (GPM) a hose can carry, the less force (PSI) is needed for the delivery.

Back to Basics: Firehose Sizes - Provident FirePlus

24.03.2017· So, when there is water flowing through a 1¾-inch hose line, it still has to travel through a 1½-inch coupling at every 50 or 100 feet; this small reduction in the hose coupling diameter adds some friction loss overall, but the amount is inconsequential in comparison to the amount of water that can be delivered at a lower operating pressure with a 1¾-inch hose line, says Fire Rescue 1.
