Chilled water pipe velocity
WebJul 18, 2016 · I have come across various values for maximum flow velocity of water in pipes. At university we were told that 2 m/s is the upper limit where flow becomes turbulent. In various planning reports I have read recently, 1 m/s is stated as the upper limit. I could calculate the exact velocity at which water in a specific size and type of pipeline ... WebThe water velocity in a copper tube should be kept within certain limits to avoid erosion, corrosion and excessive noise generation. in cold water systems - the velocities should not exceed 8 feet per second (2.4 m/s); in hot water systems with temperatures below 140 o F (60 o C) - the velocities should not exceed 5 feet per second (1.5 m/s); in hot water …

WebSep 30, 2024 · Re: Chilled Water Header Pipe Sizing. 08/13/2010 1:18 AM. A relatively crude way to do this is to use a rule of thumb such as water velocity = 3 m/s or 10 ft/s. A better way is to assess the length of the header and the acceptable pressure drop; and then use the Darcy-Weisbach or other commonly accepted formula. WebThe building system includes all chilled water piping in the building; the chilled water pump and all cooling coils, heat exchangers and other equipment using chilled water. ... Generally, the branch piping should be designed with a velocity of 3 to 6 FPS depending on actual length. When determining the flow in the pipe, consider what future ...
