Question

The area for two holes $A$ and $B$ are $2a$ and $a$, respectively. The holes are at height $\left(H/3\right)$ and $\left(2H/3\right)$ for the surface of water. Find the correct option(s):

• A. The velocity of efflux at hole $B$ is $2$ times the velocity of efflux at hole $A$
• B. The velocity of efflux at hole $B$ is $\sqrt{2}$ times the velocity of efflux at hole $A$
• C. The discharge is same through both the holes.
• D. The discharge through hole $A$ is $\sqrt{2}$ time the discharge through hole $B$

Answer 1

Answer: (B), (D)

The correct options are
B The velocity of efflux at hole $B$ is $\sqrt{2}$ times the velocity of efflux at hole $A$
D The discharge through hole $A$ is $\sqrt{2}$ time the discharge through hole $B$
