A garden hose is attached to a water faucet on one end and a spray nozzle on the other end.?
The water faucet is turned on, but the nozzle is turned off so that no water flows through the hose. The hose lies horizontally on the ground, and a stream of water sprays vertically out of a small leak to a height of 0.85 m. What is the gauge* pressure inside the hose? Pa?
( Recall that gauge pressure is a generic term for 'the amount by which the pressure is different from the atmospheric pressure'.
Gauge pressure
= (0.85) * (1000) * (9.8) Pa
= 8330 Pa.
