A vertical `U`-tube is spinned about the vertical axis passing through the left hand limb, with an angular speed `omega` such that the liquid columns in the limbs have heights `h` and `3h`, as shown in the figure. Find the value of to `omega`.

Length of a horizontal arm of U-tube is L and ends of both the vertical arms are open to atompsheric pressure P_(0) , A liquid of density rho 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 omega_(0) . 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 the horizontal arm of a uniform cross - section U - tube is l = 5 cm and both ends of the vertical arms are open to the surrounding pressure of "7700 N m"^(-2) . A liquid of density rho=10^(3)" kg m"^(-3) is poured into the tube such that the liquid just fills the horizontal part of the tube. Now, one of the open ends is sealed and the tube. Now, one of the open ends is sealed and the tube is then rotaed about a vertical axis passing through the other veritcal arm with angular velocity omega due to which the liquid rises up to half the length of the vertical arm. If length of each vertical arm is a = 6 cm. What is the value of omega("in rad s"^(-1)) ?

A horizontal thin tube of length 2L completely filled with a liquid of density delta rotates about a vertical axis passing through one of its end and along the diameter of its side face with an constant angular velocity omega . Two vertical thin long tubes are fitted with the horizontal tube to measure the pressure difference between points A and B which are at same horizontal level as shown. Neglect viscous forces and surfaces tension of liquid. The difference in the heights (h) of the liquid column in the two vertical thin tubes is :
