Az water Air 1 atm 1. Your gardening hose has a hose-end feeder attached for spraying insecticide or fertilizer. It works on the Bernoulli principle, similar to the atomizer we did in class-rushing water through the hose creates a lower pressure that draws up insecticide/fertilizer through the sprayer. Data: Cross sectional area of the hose at point 1 is 5.2 cm2. Speed of the water at point I is 2.8m/s. Density of water is 1000 kg/m, Density of the sprayer fluid is 900 kg/m Pressure inside the sprayer is tm. Water pressure at point is 200,000 Pa 5 cn Feeder straw oil a) If the fluid level in the sprayer is 7 cm below the hose, what is the pressure at the top of the feeder straw if the oil makes it up those 7 cm? b) What is the minimum water velocity in the hose at point 2 necessary to provide that pressure? Keep at least 4 significant figures as you subtract pressures. c) If the minimum velocity for part b) is 14.37 m/s, what is the cross sectional area Az necessary to achieve this speed?
