Length of horizontal arm of a uniform cross section `U`-tube is `l= 21 cm` and ends of both of the vertical arms are open to surrounding of pressure `10500 N//m^(2)`. A liquid of density `rho = 10^(3) kg//m^(3)` is poured into the tube such that liquid just fills the horizontal part of the tube. Now one of the open ends is sealed and the tube is then rotated about a vertical axis passing through the other vertical arm With angular velocity `omega_(0) = 10 rad//s`. If length of each vertical arm is `a = 6 cm`, calculate the length of air column in the sealed arm. (in cm)

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)) ?

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 a horizontal arm of ends of both the vertical arms pressure P_(0) = 10^(5) N//m^(2) . A liquid of density rho = 10^(3) kg //m^(3) is poured in the tube such that liquid just fills the horizontal part of the tube as a shown in Fig. Now one end of the open ends is sealed and the tube is then rotated about a vertical axis passing through the other vertical arm with angular speed omega_(0)=sqrt(40//3)rad//sec . If length of each vertical arm is a = 1 m and in the sealed end liquid rises to a height y = 1//2 m , find pressure in the sealed tube during rotation. (in xx 10^(5) N//m^(2))
