When I water flowers with my garden hose at a height of 1 m above the ground, the velocity
of the water is 4.0 m/s.
(a) What is the gauge pressure (total pressure minus atmospheric pressure) of the water
coming into the hose at ground level?
(b) What is the velocity of the water if I lift the hose to a height of 2 m off the ground to
water some hanging plants?
(c) What is the velocity of the water at a height of 1 m if I cover the hose with my hand,
reducing the area by 50%?
