In a water pistol, a piston drives water through a larger tube of radius 1.00 cm into a smaller tube of radius
1.00 mm.
(a) If the pistol is fired horizontally at a height of 1.5m, use ballistics (2-D projectile motion) to determine the
time it takes water to travel from the nozzle to ground. (Neglect air resistance and assume atmospheric
pressure of 1 atm.)
(b) If the range of the stream is 8.00m, with what speed must the stream leave the nozzle?
(c) Given the areas of the nozzle and the cylinder, use the equation of continuity to calculate the speed with
Which the plunger must be moved.
(d)What is the pressure at the nozzle?
(e)Use Bernoulli’s equation to find the pressure in the larger cylinder. Can gravity terms be neglected?
(f) Calculate the force that must be exerted on the trigger on the trigger to achieve the desired range. (The
Force that must be exerted is due to the pressure above atmospheric pressure.)
