Piping elbow irrecoverable pressure loss coefficients for moderately high Reynolds numbers
Test data is described for three different piping elbows. These include 900 elbows with radii of curvature of 12 and 1.5, and a 45{degrees} elbow with a radius of curvature of 1.2. These radii of curvature are sufficiently sharp to cause significant irrecoverable pressure losses to occur. The variation in static wall pressure was measured upstream and downstream of each elbow plus spatially around the elbow itself. Irrecoverable loss coefficients over a range of flows were obtained and correlations for the data are provided. The testing extended the Reynolds number range of the currently existing data base in various handbooks (and other references available in the open literature) by over a factor of five. Comparisons of results to predictions from the correlations of prior studies are provided.
