WebSep 5, 2024 · The flow through a connected pipe system will be less than the numbers in this chart, depending on the friction loss in the length of pipe, and the number of valves and fittings. Generally, for the blowdown discharge pipe to adjacent blowdown tanks, I use a 10% reduction in flow from the gpm flow rates in Table 1. WebSep 12, 2024 · Friction loss in 1 3/4-inch hose for 150 gpm is about 28 psi per 100 feet of hose. The answer: PDP = 100 + (2 x 28); PDP = 100 + 56; PDP = 156. To flow 150 gpm in this scenario, a pump...

WebWater velocity in copper tubes should not exceed 8 ft/s (2.4 m/s) for cold water and 5 ft/s (1.5 m/s) for hot water (up to approximately 140oF, 60oC ). If water temperatures routinely exceeds 140oF - don't exceed 2-3 ft/s (0.6-0.9 m/s). Pressure losses are calculated with the Hazen-Williams equation and a roughness coefficient c = 145.

WebApr 13, 2015 · When fluid flows inside a pipeline, friction occurs between the moving fluid and the stationary pipe wall. This friction converts some of the fluid’s hydraulic energy to thermal energy. ... Since this pipeline was calculated with a flow rate of 400 gpm, this example will calculate the head loss for 200 gpm and 800 gpm through the same 100 ...
