Web1 feb. 2016 · Q: What is the maximum flow velocity I can design RCP without cavitation? A: Velocity, by itself, does not create problems for concrete pipe within the ranges normally encountered. At velocities up to 40 feet per second, the severity of velocity-abrasion effects depends upon the characteristics of the bed load. http://abe-research.illinois.edu/courses/TSM352/lectures/open%20channel%20design.pdf
