A horizontal oriented tube AB of length ...


A horizontal oriented tube AB of length 5m rotates with a constant angular velocity 0.5 rad/s about a stationary vertical axis OO' passing through the end A. the tube is filled with ideal fluid. The end of the tube is open, the closed end B has a very small orifice. The velocity with which the liquid comes out from the hole (in m/s) is
