A tube filled with water and closed at both ends rotates uniformly in a horizontal plane about the axis OO'. The manometers fixed in the tube wall at distances ${\mathrm{r}}_1$ and ${\mathrm{r}}_2$ from the rotational axis indicate pressures $P_1$ and $P_2$ respectively. If is the ${\rho }_W$ density of water then find the angular velocity of rotation of tube.
