Question

water flows through a garden hose. at one point in the hose, where the cross sectional area is 3.56 times 10 to the negative 5th meters squared the velocity of the water is .718 m/s. the nozzle at the end of the hose decreases the cross sectional area to half of what it is in rest of the hose. assume that the density of the water remains constant.

1. what is the cross sectional area of the nozzle.

2. what is the velocity of the water as it goes through the nozzle.?

Answer #1

Water flows at 3.9 m / s through a garden hose of a diameter of
2.10 cm and emerges from a nozzle of a radius of 0.56 cm. If the
nozzle is directed vertically upward, to what height would the
water rise? Give your answer to two decimal places and remember add
unit m after the numerical value.

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?

Water flows through a horizontal pipe with a cross-sectional
area of 8 m2 at a speed of 12 m/s with a pressure of
200,000 Pascals at point A. At point B, the cross-sectional area is
6 m2
(7.5 points) Calculate the pressure at point B

Water flows through two sections of a horizontal tube. The
first section has a cross sectional area of 50 cm ^ 2 and the
second section is 10 cm ^ 2. If the velocity of water in the
thickest tube is 1.2 m / s and the pressure is 2.20 x 10 ^ 5 Pa,
find:
a- the speed of the water in the thinnest tube
b- the pressure of the water in the thinnest tube

A liquid of density 860 kg/m3 flows through a
horizontal pipe that has a cross-sectional area of 1.40 x
10-2 m2 in region A and a
cross-sectional area of 9.40 x 10-2 m2 in
region B. The pressure difference between the two regions
is 6.10 x 103 Pa. What are (a) the
volume flow rate and (b) the mass flow rate?
p.s. please box the final answers.

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?
Help! My answers are wrong, heres what I...

A cylindrical tank of cross-sectional area equal to A has one
inlet where water is flowing in, and no exits. The mass flow rate
going into the tank is represented with. The height ?of the water
inside the tank is represented by L, which is increasing with
time.
a. Use the general conservation of mass equation to show that
the following equation is true for this problem (assuming that
density varies with time):1??/???+1??/???=?/???. Include all
steps.
b. For the same...
