Question

A liquid is under stream lined motion through a horizontal pipe of non uniform cross section of the volume rate of flow at cross section a is v the volume rate of flow at cross section a/2 is
Ans:V

Answer 1

Non-compressible liquid? If so, then the equation of continuity applies.

<b> The volume flow rate is constant .</b> The velocity varies inversely as area.

so, if volume rate is constant, the answer must be V
