Question

Water is moving with a speed of 5.2 m/s through a pipe with a
cross-sectional area of 4.2 cm^{2}. The water gradually
descends 11 m as the pipe increases to 9.0 cm^{2}.
**(a)** What is the speed at the lower level?
**(b)** If the pressure at the upper level is 1.9 ×
10^{5} Pa, what is the pressure at the lower level?

Answer #1

let me know if any problem in the comment section ....

thanks..

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 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 flows through a pipe that gradually descends from a height
of 6.78 m to the ground. Near the top, the cross-sectional area is
0.4 m2, and the pipe gradually widens so that its area near the
ground is 0.8 m2. Water leaves the pipe at a speed of 16.8 m/s.
What is the difference in the water pressure between the top and
bottom of the pipe? In Pa

A pipe has a cross sectional area of 10 cm2 with an
unknown fluid, density of 1150 kg/m3 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
cm2. What is the speed of the fluid? 1 atm = 1.01 x
105 Pa.

Water flows through a pipe that gradually descends from a height of
6.78 m to the ground. Near the top, the cross-sectional area is 0.4
m2, and the pipe gradually widens so that its area near
the ground is 0.8 m2. Water leaves the pipe at a speed
of 16.8 m/s. What is the difference in the water pressure between
the top and bottom of the pipe?

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 is flowing at 5.00 m/s in a pipe where the cross section
is 4.00 cm2 and the pressure is 1.5 x 105 Pa. If the area gradually
becomes 8.00 cm2 at a point 10.0 m below the first point, find the
pressure at the second point.

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:...

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 ?
