Questions
Equal volume of two immiscible liquids of densities and 2 are filled in a vessel as shown in the figure. Two small holes are punched at depths h/2 and 3h/2 from the surface of lighter liquid. If v1 and v2 are the velocities of efflux at these two holes, then v1/v2 is
detailed solution
Correct option is D
v1=2gh2=ghFrom Bernoulli's theorem, ρgh+2ρgh2=12(2ρ)v22⇒ v2=2gh∴ v1v2=12.Talk to our academic expert!
