Water containing air bubbles flows without turbulence through a horizontal pipe which has a region of narrow cross-section. In this region the bubbles

A

Move with greater speed and are smaller than in the rest of the pipe

B

Move with greater speed and are larger in size than in the rest of the pipe

C

Move with lesser speed and are smaller than in the rest of the pipe

D

Move with lesser speed and are of the same size as in the rest of the pipe

Text Solution

Verified by Experts

The correct Answer is:
B
According to Bernoulli theorem in the region of narrow cross section of pipe KE of fluid will be greater and pressure energy will be lesser
`implies` Less pressure results into larger size of air bubble and greater KE results its greater speed.
