Length of a horizontal arm of U-tube is L and ends of both the vertical arms are open to atompsheric pressure P0, A liquid of density ρ is poured in the tube such that liquid just fills the horizontal part of the tube as shown in figure . Now one end of the opened ends is sealed and the tube is then rotated about a vertical axis passing through the other vertical arm with angular speed ω0. if length of each vertical arm is a and in the sealed end liquid rises to a height y, find pressure in the sealed tube during rotation.

A cylinderical tank of radiuus 20cm and height 50cm has water up to 30cm of height. What will be the rise in level of liquid at the periphery if the cylinder be givenan angular velocity of 10rads−1? Also determine the frequency of rotation when water just starts spilling over the sides of the vessel.
