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