A tube filled with water and closed at both ends uniformly rotates in a horizontal plane about the `OO'` axis. The manometers `A` and `B` fixed in the tube at distances `r_(1)` and `r_(2)` from rotational axis indicate pressure `p_(1)` and `p_(2)` respectively. Determine the angular velocity `omega` of rotation of the tube.
