I have a pressure surge of 30 barg on a24" line and i am finding information on calculation of loads at changes in direction scarce. Does anyone know where I can get a copy of a paper written by T. H. Chen, "Evaluating Surge Pressures in Piping System", ER&E Report EE.105E.84, December 1984. or any other ref which would shed some light on the problem.
