Question

The popular Super Soaker water guns are powered by compressed air (provided by a hand pump used by the operator.) A certain model has a cylindrical reservoir (where the water is held) 8.00 cm in diameter and a barrel (where the water leaves the gun) 1.00 cm in diameter. If aimed at the optimum angle, water leaving the barrel can hit a target 14.0 m away. If the end of the barrel is 30.0 cm higher than the reservoir, find: (a) the flow rate of the water leaving the barrel; (b) the gauge pressure of the water in the reservoir. (Assume air resistance acting on the water in flight is negligble.)
