Today’s Goal
1. Derive velocity of efflux
3. Range of Escaping liquid
2. Questions
Velocity of Efflux
H
Velocity of Efflux
Question: Equal volume of two immiscible liquids of
densities ρ and 2ρ 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 the lighter liquid. If v1 and v2 are the velocities
of efflux at these two holes, then v1/v2

Conclusions:
Question: On the opposite sides of wide vertical vessel
filled with water, two identical holes are opened, each
of area A. The height difference between them if ∆𝒉.
Find the net force on vessel due to water flowing out.
Question: Figure shows a cylindrical tank of crossection
area “A” filled fully till height H. A small hole of area “a”
is made at its bottom through which water starts
flowing. Find the time taken in which the tank will get
empty to half volume
