If a mixture of kerosene and water is left undisturbed for a while, which liquid comes to the bottom and which will be at the top? (2024)

Q. A mixture of kerosene oil and water is an example of immiscible liquids. When left undisturbed, they form separate layers of oil and water. Can you identify which liquid comes to the bottom and which will be at the top?

Q. A beaker contains water up to a height h1 and kerosene up to height h2 above water. Refractive index of water is μ1 and that of kerosene is μ2. The apparent shift in the position of the bottom of the beaker when viewed from the top is

Q. A wide vessel with a small hole at the bottom is filled with water and kerosene. Find the approximate velocity of the water flow if thickness of water layer is 30 cm and that of kerosene layer is 20 cm.
Specific gravity of kerosene =0.8.

Q. A large vessel with a small hole at the bottom is filled with water and kerosene. The height of the water column is 20 cm and that of the kerosene is 25 cm. The velocity with which water flows out of the hole is ( density of kerosene =0.8 gm /cc) ( Neglect viscous force)

Q. Water (ρ=1000 kg/m3) and kerosene (ρ=800 kg/m3) are filled separately in two identical cylindrical vessels having small heights. Both vessels have small holes at their bottom. The speed of the water and kerosene coming out of their holes are v1 and v2 respectively. Select the correct option.
