A water hose 2.85 cm in diameter is used by a gardener to fill a
28.0-liter bucket. (One liter = 1,000 cm^{3}.) The gardener
notices that it takes 1.00 min to fill the bucket. A nozzle with an
opening of cross-sectional area 0.500 cm^{2} 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 cm^{2} 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-cm^{2} 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.

A hose with a diameter of 1.6 cm is used to fill a pool
(circular in shape) of 6 m in diameter. How long will it take for
the water in the pool to reach a depth of 1.4 m, knowing that the
water flows at a speed of 0.40 m/s?
*Demonstrate all algebraic procedures*

To water the yard, you use a hose with a diameter of 3.1 cm. Water flows from the hose with a speed of 1.5 m/s. If you partially block the end of the hose so the effective diameter is now 0.55 cm, with what speed does water spray from the hose?

A fire hose has an inside diameter of 6.40 cm. Suppose such a
hose carries a flow of 40.0 L/s starting at a gauge pressure of
1.62×106N/m2 . The hose goes 10.0 m up a ladder to a nozzle having
an inside diameter of 3.00 cm. Calculate the Reynolds numbers for
flow in the fire hose and nozzle to show that the flow in each must
be turbulent.

Water flowing through a garden hose of diameter 2.75 cm fills a
24.0-L bucket in 1.30 min.
(a) What is the speed of the water leaving the end of the
hose?
m/s
(b) A nozzle is now attached to the end of the hose. If the nozzle
diameter is one-third the diameter of the hose, what is the speed
of the water leaving the nozzle?
m/s

A
garden hose with a diameter of 1.8 in. has water flowing in it with
a speed of 0.57 m/s and a pressure of 1.3 atmospheres. At the end
of the hose is a nozzle with a diameter of 0.54 in.
Part A) Find the speed of the water in the nozzle.
Part B) Find the pressure in the nozzle.

A garden hose with an internal diameter of 2.7 cm is connected
to a (stationary) lawn sprinkler that consists merely of a
container with 26 holes, each 0.33 cm in diameter. If the water in
the hose has a speed of 0.86 m/s, at what speed does it leave the
sprinkler holes?

2. A garden hose attached to a nozzle is used to fill a 15-gal
bucket. The inner diameter of the hose is 1.5 cm, and it reduces to
0.8 cm at the nozzle exit. If it takes 50 s to fill the bucket with
water (density = 1 kg/L), determine
(a) the volume and mass flow rates of water through the hose,
and
(b) the average velocity of water at the nozzle exit.

An open cylinder 30 cm in diameter and 80 cm high containing
water is rotated about its vertical axis at a speed of 240 rpm. If
the Cylinder is brought to rest now, what would be the depth of
water in it? If the speed is increased to 420 rpm. How much water
will be left in the cylinder in liters? Specific Question If the
speed is increased to 420 rpm. How much water will be left in the
cylinder...

a- Water enters a house through a pipe with inside diameter of
3.0 cm at an absolute pressure of 5.0 X 105 Pa. A 1.5 cm diameter
pipe leads to the second-floor bathroom 6.0 m above. When the flow
speed at the inlet pipe is 2.0 m/s
find:
- Flow speed (velocity) of the water in the bathroom
- Pressure water in the bathroom?
- Calculate the volume flow rate in the bathroom.

Water is flowing in the pipe shown in the figure below, with the
7.70-cm diameter at point 1 tapering to 3.45 cm at point 2, located
y = 11.5 cm below point 1. The water pressure at point 1 is 3.20 ✕
104 Pa and decreases by 50% at point 2. Assume steady, ideal flow.
What is the speed of the water at the following points? Point 1?
Point 2?
