Water enters through end A with a speed ...

Water enters through end A with a speed `v_1` and leaves through end B with a speed `v_2` of cylindrical tube AB. The tube is always completely filled with water. In case I the tube is horizontal, in case II it vertical with the end A upward and in case III it is vertical with the end B upward. We have `v_1=v_2`for

A

case I

B

case II

C

case IlI

D

each case

Text Solution

Verified by Experts

The correct Answer is:
D
This happens in accordance with equation of continuity and this equation was derived on the principle of conservation of mass and it is true in every case, either tube remain horizontal or vertical.
