Rolling of Steel in a Modern Long Product Rolling Mill
Roll pass design is an essential part of long product rolling process since the long products are rolled between the shaped rolls in the long product rolling mills Roll pass design generally means the cutting of grooves in the roll body through which steel to be rolled is made to pass sequentially to get the desired contour and size.

Fluid velocity in a vertical pipePhysics Stack Exchange
According to the continuity equation the velocity of water going into the pipe seems to be the same as the velocity of water coming out But according to Bernoulli s equation P a t m 1 2 ρ v 1 2 ρ g L = P a t m 1 2 ρ v 2 2 v 2 = v 1 2 2 g L Which means that the e water would come out faster which makes much sence.
