In a water pistol, a piston drives water through a larger tube of area A, into a smaller tube of area A2 as shown in the figure below. The radius of the large tube is 1.40 cm and that of the small tube is 1.10 mm. The smaller tube is 3.00 cm above the larger tube. A2 (a) If the pistol is fired horizontally at a height of 1.60 m, determine the time interval required for water to travel from the nozzle to the ground. Neglect air resistance and assume atmospheric pressure is 1.00 atm. .58 (b) If the desired range of the stream is 7.50 m, with what speed v2 must the stream leave the nozzle? 12.9 m/s (c) At what speed v, must the plunger be moved to achieve the desired range? 7.9 X m/s (d) What is the pressure at the nozzle? 1.01e5 Pa (e) Find the pressure needed in the larger tube. X Pa (f) Calculate the force that must be exerted on the trigger to achieve the desired range. (The force that must be exerted is due to pressure over and above atmospheric pressure.) X N

Water runs into a fountain, filling all the pipes, at a steady rate of 7.53×10−2 m3/s. How fast will it shoot out of a hole 4.49 cm in diameter? At what speed will it shoot out if the diameter of the hole is three times as large?
You’re holding a hose at waist height and spraying water horizontally with it. The hose nozzle has a diameter of 1.80 cm, and the water splashes on the ground a distance of 0.970 m horizontally from the nozzle. Suppose you now constrict the nozzle to a diameter of 0.750 cm; how far horizontally from the nozzle will the water travel before hitting the ground? (Ignore air resistance.)
