  Fluid Dynamics.-  

(1) Consider an open tank containing water until a height  H. A small hole is open in its lateral wall at a height  h  from the bottom.  Determine: (a) the speed of water escaping through the hole (b) the horizontal range of the escaping water. 


The descent velocity of the water in the tank is so small compared with the escape velocity through the lateral hole, that the former may be considered zero.   Since tank is open at its top and at the hole, at both places the pressure is that of the atmosphere. Surface of the water: subscript 1.         Hole in tank wall: subscript 2
