Question

Calculate the Reynolds number for the flow of water to a nozzle
with a radius of 0.270 cm in a garden hose with the radius of 0.950
cm when the nozzle is attached to the hose the flow rate through
hose and nozzle is 0.490 L per second assume the temperature of
water is 20°C

A. a nozzle with the radius of 0.270

Can the flow be laminar

B. A garden hose with the radius 0.950 cm

Can the flow be laminar

Answer #1

A nozzle with a radius of 0.24 cm is attached to a garden hose
with a radius of 0.91 cm that is pointed straight up. The flow rate
through hose and nozzle is 0.45 L/s. Part a. Calculate the maximum
height to which water could be squirted with the hose if it emerges
from the nozzle in m. Part b. Calculate the maximum height (in cm)
to which water could be squirted with the hose if it emerges with
the...

Question 3. A garden hose attached with a nozzle is
used to fill a 25-gal (1gal =3.785L) bucket.
The water flows in the hose with the inner diameter of 1.1 in, and
exits at the nozzle at 50 m/s of
velocity. If it takes 0.8 min to fill the bucket with water,
determine
i. the volume and mass flow rates of water through the hose,
ii. the inner dimeter at the nozzle exit?
iii. the kinetic energy changes through the...

Water flowing through a garden hose of diameter 2.78 cm fills a
22.0 L bucket in 1.50 min.
(a) What is the speed of the water leaving the end of the
hose?
(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?

Water flowing through a garden hose of diameter 2.73 cm fills a
21.0-L bucket in 1.35 min.
(a) What is the speed of the water leaving the end of the
hose?
(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?

The water is leaving the nozzle of a hose with a volume flow
rate of 0.50 m3/s. Assume there are no leaks and the
nozzle has a circular opening with diameter of 4.5 mm.
1) How fast is the water leaving the nozzle of a
hose? (Express your answer to two significant
figures.)
Note: 31453.96 is NOT the correct
answer

Water flows at the rate of 3.48 kg/s through a hose with a
diameter of 3.00 cm.
(a) What is the speed of water in this hose?
(b) If the hose is attached to a nozzle with a diameter of 0.750
cm, what is the speed of water in the nozzle?
(c) Is the number of kilograms per second flowing through the
nozzle greater than, less than, or equal to 3.48 kg/s?

A rectangular horizontal-flow sedimentation basin in a
conventional water treatment plant has been designed to treat a
flow of 50,000 m3 /day. It has a length = 80 m, width = 20 m, and
depth = 3.6 m. For this problem, assume temperature = 20 °C
(density of water = 103 kg/m3 and viscosity = 10-3 kg/m·s) and
laminar flow.
a. What is the hydraulic detention time? Does this meet the
typical criteria for this type of sedimentation basin?
b....

A student fills a tank of radius .15m with water to a height of
.5m and pokes a small, 1.0 cm diameter hole at a distance 0.03m
from the bottom of the tank. The water flows out of the small hole
into an empty, 0.2 m diameter container placed below the
tank. The student uses a garden hose to keep the water
level in the tank at the original height.
What is the velocity of the water as it leaves the...

How
to calculate Reynolds number, for a mixture of two liquids flowing
through a pipe (glycerol 50% of total volume and water 50% of total
volume) if velocity isn't given, but temperature, internal diameter
and pressure gradient per metre is given.
