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.

Length of a horizontal arm of U-tube is L and ends of both the vertical arms are open to atompsheric pressure P0 Water is retained by a curved gate AB. Compute the horizontal and vertical component of the resultant of the hydrostatic pressure dsitribution on the gate AB which is a quarter of a cylinder. Assume that the gate is 4m wide.
