A cylindrical vessel of area of cross-section A is filled with water to a height H. It has capillary tube of length l and radius r fitted horizontally at its bottom. If the coeffiecient of viscosity of water is `eta`, then time required in which level will fall to a height `(H)/(2)` is (density of water is `rho`)
