The critical velocity of a slurry flow in a pipe is that velocity in which particles start forming a sliding bed on the bottom of the pipe. This will cause the flow to become unstable and the pipe will eventually clog. General slurry pipeline practice is to design the pipe velocity to exceed the critical velocity by at least 30%.
