A light cylindrical tube 'T' of length `l` and radius 'r' containing air is inverted in water (density d). One end of the tube is open and the other is closed A block 'B' of density 2d is kept on the tube as shown in the figure. The tube stays in equilibrium in the position shown. (Assume the atmosphere pressure is to be `P_(0)`)
Assume that density of air is very small than density of block and water. Pick up the correct statement (s)

A L Shaped tube containing liquid of density pis accelerated horizontally with acceleration as shown in the figure. The end of tube B is closed while end A is open. If the atmospheric pressure is Po . Then the pressure at B is :

Figure shows a capillary tube of radius r dipped into water. If the atmosphere pressure is P_0 , the pressure at point A is

A light cylinderical tube of length L=1.5m and radius v=(1)/sqrt(pi)m is open at one end. The tube containing air is inverted and pushed inside water as shown in figure. A block made of material of relative density 2 haas been placed on the flat upper surface of the tube and the whole system is in equilibrium Neglect the weight of air inside the tube and find the volume of block placed on the tube.

Figure shows as thin tube open at one end rotating with constant angular speed omega . The other end of the tube has a small opening. Tube contains a fluid of density rho which effuses with speed u relative to the tube. Let rho_(A) be the pressure at the point in the tube just behind the opening. Assume the atmospheric pressure to be p_(0) and pick correct option(s) for the instant when h=l/2

The value of end correction for the pipe open at both the ends is a (If the d is the inner diameter of the tube and r is the radius of the tube .)

A narrow tube of length l and radius r is sealed at one end. Its open end is brought in contact with the surface of water while the tube is held vertical. The water rises to a height h in the tube. The contact angle of water with the tube wall is theta , density of water is rho and the atmospheric pressure is P_(o) . Find the surface tension of the liquid. Assume that the temperature of air inside the tube remains constant and the volume of the meniscus is negligible.
