A liquid flow...

Question

A liquid flows in a tube from left to right as shown in figure $A_{1}$ and $A_{2}$ are the cross-section of the portion of the tube as shown. Then the ratio of speed $ν_{1} / v_{2}$ will be:

Solution

The correct option is B $\frac{A_{2}}{A_{1}}$
From the equation of continuity,
Flow rate is constant
$Q = c o n s t a n t$
$A_{1} v_{1} = A_{2} v_{2}$
$\frac{v_{1}}{v_{2}} = \frac{A_{2}}{A_{1}}$
The correct option is B.
