A horizontally oriented tube AB of length l = 2.5 m rotates with a constant angular velocity ω = 5 rad s about a stationary vertical axis OO’ passing through the end A (fig). The tube is filled with an ideal fluid. The end A of the tube is open, the closed end B has a very small orifice. Find the velocity of the fluid relative to the tube as a function of the column ‘height’ h = 1 m.
