Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Reynolds number is used to find out a flow pattern in a liquid. It is the ratio of inertial forces to viscous forces.
$R e y n o l d^{'} s n u m b e r = \frac{i n e r t i a l f o r c e s}{v i s c o u s f o r c e s}$ .
If this ratio is greater than 2000 inertial forces are dominant and the flow becomes turbulent.
