A cylindrical vessel of base radius R and height H has a narrow neck of height h and radius r at one end (see figure). The vessel is filled with water (density`rho_(w)`) and its neck is filled with immiscible oil (density `rho_(O)`). Then the pressure at

The centr of mass of a right circular coneof height h, radius R and constant density rho is at

A cylindrical vessel of area of cross-section A and filled with liquid to a height of h_(1) has a capillary tube of length l and radius r protuding horizontally at its bottom. If the viscosity of liquyid is eta and density rho . Find the time in which the level of water in the vessel falls to h_(2) .

A cylindrical vessel of radius R and height H and open at the top is completely filled with y . A small circular hole of radius r is made near the bottom of vessel . The time taken for 25 % of water to flow out is

A beaker is filled with a liquid of density rho upto a height h If the beaker is at rest, the mean pressure at the walls is:

A beaker is filled with a liquid of density rho upto a height h If the beaker is at rest, the mean pressure at the walls is:

A vessel of length l, breadth b and height h is filled completely with a liquid of density d (see figure) Calculate the thrust on each surface of the cube.
