Water enters through end$\mathrm{A}$with speed${\text{v}}_1$and leaves through end$\mathrm{B}$with speed${\text{v}}_2$of a cylindrical tube$\mathrm{AB}$. The tube is always completely filled with water. In case$\mathrm{I}$tube is horizontal and in case$\mathrm{II}$it is vertical with end$\mathrm{A}$upwards and in case$\mathrm{III}$it is vertical with end$\mathrm{B}$upwards. We have${\text{v}}_1={\text{v}}_2$for
