(6%) Problem 14: A child fills up a water gun with water from a pool. She holds the gun just completely submerged at an angle of 0 = 35 from horizontal while pulling on the handle to suck water into the water gun tank. The tank has a length of L = 0.55 meters, and the nozzle of the gun has a cross-sectional area A that is 210 times smaller than the area of the tank, 42. water. 25% Part (a) Write an expression for the max absolute pressure at the tip of the water gun P 100% using Po as the atmospheric pressure and p as the density of 25% Part (b) What is this pressure P 100%; in pascals? A 25% Part (c) The girl pulls the plunger so that the water evenly fills the length of the tank in a time t. Determine the speed of the water moving through the nozzle, in terms of this time, the length L, and the areas A1 and A2. A 25% Part (d) If the girl pulls the plunger so that the pressure in the tank of the water gun is 0.17Po and the tanks fill in a time 41 s, what is the pressure in the nozzle during this process, in pascals.
