A water hose 2.85 cm in diameter is used by a gardener to fill a
28.0-liter bucket. (One liter = 1,000 cm3.) The gardener
notices that it takes 1.00 min to fill the bucket. A nozzle with an
opening of cross-sectional area 0.500 cm2 is then
attached to the hose. The nozzle is held so that water is projected
horizontally from a point 1.00 m above the ground. Over what
horizontal distance can the water be projected?
4.33 m *CORRECT*
EXERCISE HINTS: GETTING STARTED | I'M STUCK!
Use the values from PRACTICE IT to help you work this exercise. The nozzle is replaced with a Y-shaped fitting that splits the flow in half. Garden hoses are connected to each end of the Y, with each hose having a 0.420 cm2 nozzle.
(a) How fast does the water come out of one of the nozzles?
4.67 m/s *INCORRECT*
Some of the information you need is in the example. m/s
(b) How far would one of the nozzles squirt water if both were
operated simultaneously and held horizontally 1.00 m off the
ground? (Hint: Find the volume flow rate through each
0.420-cm2 nozzle, then follow the same steps as
before.)
2.11 m *INCORRECT*
Your expression is correct, but since your answer to part (a) is
wrong, this answer is wrong too.
