A liquid is flowing through a pipe of non-uniform cross-section. At a point where area of cross-section of the pipe is less, match the following columns.

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
From, `A_(1)v_(1)=A_(2)v_(2) " or " v prop (1)/(4)`
At a point where area of cross-section is less, volume of liquid flowing per second is same but speed is more. Therefore, here kinetic energy is more or the pressure will be less.
