In a very big closed tank, the absolute pressure of the air above the water is 6.41 x 105 Pa. The water leaves the bottom of the tank through a nozzle that is directed straight upward. The opening of the nozzle is 4.79 meter below the surface of the water.
(a) Calculate the speed at which the water leaves the nozzle.
(b) Neglect viscous effects and air resistance, calculate the height (relative to the submerged end of nozzle) to which the water rises.
