WebPer the Copper Tube Handbook ( www.copper.org ), once the fluid temperature exceeds 140°F, the velocity needs to slow down to 2 to 3 fps, as the water becomes more aggressive the hotter it becomes. To slow the velocity of water in a given pipe, either (a) the flow rate must reduce or (b) the pipe must get larger. The values in the UPC are ... WebFeb 20, 2024 · There is no maximum requirement in NFPA 13 or in building codes for hydraulic calculations. However, NFPA handbooks tell you to use velocities between 10-20 ft/s. The reason is that the values of the friction loss coefficients used are accurate only if the flow velocity is close to that at which the value of C was measured. Reply.

"WebMar 3, 2015 · v = V A. If you use cubic feet per second and feet squared, the result will be in feet per second. HOWEVER. The actual velocity of a fluid in a pipe is a function of the position in the pipe. For laminar flow, the velocity follows a parabolic profile, with the points near the wall being almost stationary, and the points in the middle going fastest. " - Flow velocity fps
