A container of large uniform cross-sectional area A resting on a horizontal surface, holes two immiscible, non-viscon and incompressible liquids of densities d and 2d each of height `H//2` as shown in the figure. The lower density liquid is open to the atmosphere having pressure `P_(0)`. A homogeneous solid cylinder of length `L(LltH//2)` and cross-sectional area `A//5` is immeresed such that it floats with its axis vertical at the liquid-liquid interface with length `L//4` in the denser liquid,

The cylinder is then removed and the original arrangement is restroed. a tiny hole of area `s(sltltA)` is punched on the vertical side of the container at a height `h(hltH//2)`. As a result of this, liquid starts flowing out of the hole with a range x on the horizontal surface.
The initial speed of efflux without cylinder is

Answer

(i). (a). `D=(5)/(4)d`
(b). `P=P_(0)+(1)/(4)(6H+L)dg`
(ii). (a). `v=sqrt((g)/(2)(3H-4h))`
(b). `x=sqrt(h(3H-4h))`
(c). `x_(max)=(3)/(4)H`
