Question

A pipe has a cross sectional area of 10 cm^{2} with an
unknown fluid, density of 1150 kg/m^{3} moving at a speed
of 3 m/s and has a pressure of 1.4 atm. The pipe then lowers down
2.5 meters and narrows to a cross sectional area of 2.5
cm^{2}. What is the speed of the fluid? 1 atm = 1.01 x
10^{5} Pa.

express your answer with the correct units

Determine the pressure in atm of the fluid in the pipe in the
second region. 1 atm = 1.01 x 10^{5} Pa.

Answer #1

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

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?

At a soft drink bottling plant, a horizontal section of pipe
carrying citric acid in liquid form goes from a cross-sectional
area of 8.00 cm2, fluid flow speed of 330 cm/s, and pressure of
1.40 105 Pa to a section of pipe with a cross-sectional area of
3.60 cm2. The density of the citric acid is 1660 kg/m3. For the
section of smaller pipe, determine the liquid flow speed and the
liquid pressure.

9) If the pressure in a pipe with a
cross sectional area of 2.0 m2 is 150,000 Pa and the
velocity of the fluid is 5.0 m/sec, what will be the pressure in
the pipe at another point that is 4.0 m higher and has a cross
sectional area of 6.0 m2 ?

A horizontal pipe has a cross-sectional area of
0.025m2 at the entrance and 0.010m2 at the
exit. If water enters the pipe at a speed of 2.5 m/s and a gauge
pressure of 46kPa, what is the gauge pressure of the water at the
exit end? The density of water is 1000 kg/m3.

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.

The pressure at the bottom of a cylindrical container with a
cross-sectional area of 58.5 cm2 and holding a fluid of
density 500 kg/m^3 is 115 kPa.
(a) Determine the depth of the fluid.
(b) Determine the pressure at the bottom of the container if an
additional 1.80 10-3 m3 of this fluid is
added to the container. (Give your answer to at least 3 significant
figures.)

A liquid (ρ = 1.65 g/cm3) flows through a horizontal pipe of
varying cross section as in the figure below. In the first section,
the cross-sectional area is 10.0 cm2, the flow speed is 246 cm/s,
and the pressure is 1.20 105 Pa. In the second section, the
cross-sectional area is 4.50 cm2. (a) Calculate the smaller
section's flow speed. m/s (b) Calculate the smaller section's
pressure. Pa

Water is flowing in a straight horizontal pipe of variable cross
section. Where the cross-sectional area of the pipe is 2.90·10-2
m2, the pressure is 10.90·105 Pa and the velocity is 0.310 m/s. In
a constricted region where the area is 10.30·10-4 m2, what is the
velocity? (in m/s)
A: 1.97 B: 2.86 C: 4.15 D: 6.02 E: 8.73 F: 1.27×101 G: 1.84×101
H: 2.66×101 Tries 0/12
What is the pressure (in Pa)? (Assume an ideal fluid)
A: 8.24×105 B:...
