A horizontally oriented tube AB of length l rotates with a constant angular velocity omega about a stationary vertical axis OO^' passing through the end A (figure). 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.

A horizontal oriented tube AB of length l rotates with a constant angular velocity omega about a stationary vertical axis OO' passing thorugh the end A figure. 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.

Find the mass of a mole of colloid particles if during their centrifuging with an angular velocity omega about a vertical axis the concentration of the particles at the distance r_2 from the rotation axis is eta times greater than that at the distance r_1 (in the same horizontal plane). The densities of the particles and the solvent are equal to rho and to rho_0 respectively.
