A horizontal tube has different cross-sectional areas at points

A

and

B

. The diameter of

A

4 \mathrm{~cm}

and that of

B

2 \mathrm{~cm}

. Two manometer limbs are attached at

A

and

B

. When a liquid of density

8.0 \mathrm{~g} \mathrm{~cm}^{-3}

flows through the tube, the pressure difference between the limbs of the manometer is

8 \mathrm{~cm}

. Calculate the rate of flow of the liquid in the tube.

View answer and explanation

Correct option: A

406 \mathrm{~cm}^3 \mathrm{~ms}^{-1}

Option A (

406 \mathrm{~cm}^3 \mathrm{~ms}^{-1}

) is correct because it is the calculated rate of flow using the given parameters and the formula for fluid flow in a tube with varying cross-sections.
