Elbow friction loss
WebJan 30, 2024 · The pressure drop across 90deg sharp-angled miter elbows connecting straight circular pipes is studied in a bespoke experimental facility by using water and air as working fluids flowing in the range of bulk Reynolds number 500<60,000. To the best of our knowledge, the dependence on the Reynolds number of the pressure drop across …

WebSep 2, 2024 · Discoloration of the elbow or areas near the elbow occurs. A bluish, purplish, or blackish color may indicate bleeding into, or near, the elbow. A reddish color may be … WebThe friction loss would be twice as much if the pipe was 200 ft. and 10 times as much for a 1000 ft. length of pipe, - IF - the average flow rate is maintained at 100 gpm. When a pipe has a C factor other than 100, it is possible to adjust back to a C factor of 100 by multiplying the flow by 100/C, and then go to the table when you have a newly ...
WebJun 1, 2008 · For this size of elbow we will use a radius of 115mm set at 60mm apart without any trailing extensions. For this design, the loss coefficient Co is 0.15. The velocity pressure for a duct 800mm x 400mm with an actual velocity of 7.03m/s is 29.8Pa. Therefore the loss through the elbow = 29.8 x 0.15 ? 4.5Pa.
