A liquid is kept in a cylindrical vessel which is rotated along its axis. The liquid rises at the sides (figure). If the radius of the vessel is 0.05 m and the sped of rotation is , find the difference in the height of the liquid at the centre of the vessel and its sides in cm is

According to Bernoulli’s Theorem; =constant. Near the ends, the velocity of liquid is higher so that pressure is lower as a result the liquid rises at the sides to compensate for this drop of pressure

Hence,
