5) Aperson, shown, holds a garden hose above her head so it is 1.50 meters above level grotnrd. Whm the water is turned on to its highest speed, the volume ow rate of water into and out of the hose is 2.00 gallons every 15.0 seconds. Additionally, when the water enters the hose at the spigot, it enters the circular cross section of the hose which has a diameter 1.00 inch {or 2.54 cm}. Upon leaving the hose, the water passes horizontally through a nozzle with a diameter of only 0.400 cm and moves parallel to the ground as it passes through sea level air. {15 pninn} Some useful conversinnr 1 gallon = 3.19 liters 1 m3 = 2154.2 gallons [a]: Calculate the amount of time (in hours) it would take this hose, if left running continuously at the rate given ahove, to ll an empty 20,000 gallon swimming pool. [3. points} {h} Calculate the volume ow rate of the water in units of cubic meters per second. {2 points} {c} Calculate the speed of the water in the hose just as it enters it from the spigot {valve} at the wall when the person turns the water on. [3 points] (d) Calculate the water pressure {in units of atm] inside the hose just as it enters the hose from the spigot. [1' points]
