Question

A liquid is under stream lined motion through a horizontal pipe of non uniform cross section. If the volume rate of flow at cross section ' is V,the volume rate of flow at cross section $\frac{a}{2}$ is

• A. $\frac{v}{2}$
• B. $V$
• C. $\frac{v}{4}$
• D. $2V$

Answer 1

The correct option is B $V$

We Know, Volume of water passing through a pipe

in a second is constant.

the volume rate of fow at cross section $9/4$

is also,V

Option (B) is correct.
