Two non-mixing liquids of densities rho ...

Two non-mixing liquids of densities `rho` and `(n gt1)` are put in a container. The height of each liquid is `h`. A solid cylinder of length `L` and density `d` is put in this container. The cylinder floats with its axis vertical and length `pL(p lt 1)` in the denser liquid. The density `d` is equal to :

A

[1+(n + l)p]p

B

[2 + (« +l)p]p

C

[2+(n-l)p]p

D

[l +(n-l)p]p

A container of a large uniform cross-sectional area A resting on a horizontal surface holds two immiscible, non viscous and incompressible liquids of densities d and 2d , each of height H//2 as shown in figure. The lower density liquid is open to atmosphere. A homogeneous solid cylinder of length L(L lt (H)/(2)) , cross-sectional area A//5 is immersed such that it floats with its axis vertical of the liquid-liquid interface with length L//4 denser liquid. Determine (a) density D of the solid and (b) the total pressure at the bottom of the container. (Atmospheric pressure = P_0 ). .

Fluids at rest exert a normal force to the walls of the container or to the sruface of the Body immersed in the fluid. The pressure exerted by this force at a point inside the liqid is the sum of atmospheric pressure and a factor which depends on the density of the liquid, the acceleration due to gravity and the height of the liquid, above that point. The upthrust acting on a body immersed in a stationary liquid is the net force acting on the body in the upward direction. A number of phenomenon of liquids in motion can be explain by Bernoulli's theorem which relates the pressure, flow speed and height for flow of an ideal incompressible fluid.
