Question

Water enters through an end A with speed $v_{1}$ and leaves through end B with speed of $v_{2}$ of a cylindrical tube AB. The tube is always filled completely with water. In case $I$ tube is horizontal, in case $I I$ it is vertical with end A upwards and in case $I I I$ it is vertical with end B upwards. We have $v_{1} = v_{2}$ for

Solution

The correct option is D Each case
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.
So, option (d) is correct.
