Test data is described for two ninety degree elbows that are in series for a piping network. Both elbows had a radius of curvature of 1.2. Three relative angles and seven different separation distances were investigated. The overall irrecoverable pressure loss for the two elbows is characterized relative to the irrecoverable pressure loss for a single elbow. In addition to providing design guidance relative to the net irrecoverable pressure loss for multiple elbows, the data provides a data base for helping qualify computational fluid dynamics (CFD) computer codes used to predict the irrecoverable pressure loss in piping systems.
