A sealed tank containing a liquid of density rho moves with horizontal acceleration a as shown in the figure. The difference in pressure between two points A and B will be

On the opposite sides of a wide vertical vessel filled with water two identical holes are opened each having the cross-sectional area S=0.50cm^(2) the height difference between them is equal to Deltah=51cm find the resultant force of reaction of the water flowing out of the vessel.

A small uniform tube is bent into a circle of radius r whose plane is vertical. Equal volumes of two fluids whose densities are rho and sigma(rhogtsigma) fill half the circle. Find the angle that the radius passing through the interface makes with the vertical.

In a U-tube if different liquids are filled then we can say that pressure at same level of same liquid is same. Q. In a U-tube 20 cm of a liquid of density rho is on left hand side and 10 cm of another liquid of density 1.5 rho is on right hand side in between them there is a third liquid of density 2rho what is the value of h .

When a vertical capillary of length l with a sealed upper end was brought in contact with the surface of a liquid, the level of this liquid rose to the height h . The liquid density is rho , the inside diameter the capillary is d , the contact angle is theta , the atmospheric pressure is rho_(0) . Find the surface tension of the liquid. (Temperature in this process remains constant.)

Two vessels have the same base area but different shapes . The first vessel takes twice the volume of water that the second vessel requires to fill upto a particular common height . Is the force exerted by the two water on the base of the vessel the same in the two cases ? If so , why do the vessels filled with water to that same height give different readings on a weighing scale ?

A satellite moves eastwards very near the surface of the Earth in equitorial plane with speed (v_(0)) . Another satellite moves at the same height with the same speed in the equatorial plane but westwards. If R =radius of the Earth and omega be its angular speed of the Earth about its own axis. Then find the approximate difference in the two time period as observed on the earth.

A U tube is rotated about one of it's limbs with an angular velocity omega . Find the difference in height H of the liquid (density rho ) level, where diameter of the tube dlt lt L .

A cylindrical vessel of height 500mm has an orifice (small hole) at its bottom. The orifice is initially closed and water is filled in it up to height H. Now the top is completely sealed with a cap and the orifice at the bottom is opened. Some water comes out from the orifice and the water level in the vessel becomes steady with height of water column being 200mm. Find the fall in height(in mm) of water level due to opening of the orifice. [Take atmospheric pressure =1.0xx10^5N//m^2 , density of water=1000kg//m^3 and g=10m//s^2 . Neglect any effect of surface tension.]
