Water flows out of a garden hose which has an opening 2.20 cm in diameter. the flow is such that the water fills a 2.50 gallon bucket in 30.0 seconds. the hose is supplied by an underground pipe 1.10 meter below the exit of the hose. the diameter of the underground pipe is 2.0 inches. (a) what is the flow speed of the water as it exits the hose? (b) what is the flow speed in the underground pipe? (c) what is the gauge pressure in the underground pipe?
