Transcribed Image Text:You wash your roof with a water hose at a height of 8.0 m above the ground. You connect two garden hoses to reach the roof, one
with a radius of 0.40 cm and the other with a radius of 0.50 cm. The smaller hose is held on the roof and the larger hose is attached
to a faucet at ground level, as shown in the image below.
You want the exit speed of the water out of the smaller hose on the roof to be 6.0 m/s, and you know the water moves in the large
hose but do not know the speed of the water within the large part of the hose.
What should the absolute pressure
Pascals) in the large hose be at ground level? Atmospheric pressure is 1.01x105 Pa.
Vz= 6.0 m/s
r;=0.40 cm
8.0 m
r2=0.50 cm
