Question

In a water pistol, a piston drives water through a larger tube
of area *A*_{1} into a smaller tube of area
*A*_{2} as shown in the figure below. The radius of
the large tube is 1.20 cm and that of the small tube is 1.50 mm.
The smaller tube is 3.00 cm above the larger tube.

(a) If the pistol is fired horizontally at a height of 1.10 m,
determine the time interval required for water to travel from the
nozzle to the ground. Neglect air resistance and assume atmospheric
pressure is 1.00 atm.

s

(b) If the desired range of the stream is 7.60 m, with what speed
*v*_{2} must the stream leave the nozzle?

m/s

(c) At what speed *v*_{1} must the plunger be moved
to achieve the desired range?

m/s

(d) What is the pressure at the nozzle?

Pa

(e) Find the pressure needed in the larger tube.

Pa

(f) Calculate the force that must be exerted on the trigger to
achieve the desired range. (The force that must be exerted is due
to pressure over and above atmospheric pressure.)

In a water pistol, a piston drives water through a larger tube
of area A1 into a smaller tube of area A2 as shown in the figure
below. The radius of the large tube is 1.50 cm and that of the
small tube is 1.10 mm. The smaller tube is 3.00 cm above the larger
tube.
(a) If the pistol is fired horizontally at a height of 1.10 m,
determine the time interval required for water to travel from the...

1. Water moves through a pipe with a cross-section area of 4.20
m^2 at speed of 2.25m/s with pressure P1 of 1.65x 10^5 Pa. If the
cross section area at p2 is 1.80m^2 and the water has traveled up a
distance of y=3.30 m, what is the pressure P2?
2. A 2.50 cm diameter piston pushes on an incompressible liquid
with force F1. An object with a mass of 1.80x10^3kg sets on the
second piston with a diameter of 3.20m....

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

syringe?
b) If aimed vertically, how high will the water go?
c) If the syringe is tipped...

The tube shown has a length of 2.00 m and a diameter of 1.00 mm.
Water at 40° C is flowing through the tube.
For water at 40° C:
A) What pressure difference is required to give the water a flow
speed of 4.0 m/s? (Give your answer in units of Pa.)
B) What force applied to the end of the tube will produce this
pressure? (Give your answer in units of N.)
C) What is the volume flow rate...

Water is moving with a speed of 4.6 m/s through a pipe with a
cross-sectional area of 3.5 cm2. The water gradually descends 8 m
as the pipe increases in area to 8.3 cm2.
(a) What is the speed at the lower level? m/s
(b) If the pressure at the upper level is 1.7 ✕ 105 Pa, what is
the pressure at the lower level? Pa
please show work and answer

Given: The viscosity is negligible. Atmospheric pressure is
101300 Pa. Water flows at speed of 5.9 m/s through a horizontal
pipe of diameter 3.3 cm. The gauge pressure P1 of the water in the
pipe is 1.6 atm. A short segment of the pipe is constricted to a
smaller diameter of 2.4 cm.
What is the gauge pressure of the water flowing through the
constricted segment? Answer in units of atm.

Water is moving with a speed of 5.2 m/s through a pipe with a
cross-sectional area of 4.2 cm2. The water gradually
descends 11 m as the pipe increases to 9.0 cm2.
(a) What is the speed at the lower level?
(b) If the pressure at the upper level is 1.9 ×
105 Pa, what is the pressure at the lower level?

Water is moving with a speed of 5.5 m/s through a pipe with a
cross-sectional area of 4.6 cm2. The water gradually descends 11 m
as the pipe increases to 9.0 cm2. (a) What is the speed at the
lower level? (b) If the pressure at the upper level is 1.7 × 105
Pa, what is the pressure at the lower level?

Water circulates through a hot-water heating system in a house. The
water leaves the basement with a speed of 0.5 m/s through a
4-cm-diameter pipe, under a total pressure of 3Patm. (Assume that
all the pipes have circular cross-sectional areas and that the
pipes don't "branch off" at any point.) a) If the pipe on the
second floor of the house has a smaller radius than the basement
pipe, will the speed of the water in the second-floor pipe be...
