Question

There is a pipe with a radius of 47 cm. Water is flowing thorugh this pipe and ends up 4.7 m below the starting point with a radius of 83 cm. The water enters at the starting point with a velcity of 4.9 m/s. What is the pressure difference between the starting point and endpoint of the pipe assuming that the density of water is 1000 kg/m^3.

Answer #1

Water flowing out of a horizontal pipe emerges through a nozzle.
The radius of the pipe is 2.3 cm, and the radius of the nozzle is
0.41 cm. The speed of the water in the pipe is 0.74 m/s. Treat the
water as an ideal fluid, and determine the absolute pressure of the
water in the pipe.

Water flowing out of a horizontal pipe emerges through a nozzle.
The radius of the pipe is 1.8 cm, and the radius of the nozzle is
0.51 cm. The speed of the water in the pipe is 0.70 m/s. Treat the
water as an ideal fluid, and determine the absolute pressure of the
water in the pipe.

A 4.70 cm radius pipe has ethanol flowing through it at 6.00
m/s. The pipe then rises by 7.00 m and increases in radius to 11.3
cm. The pipe then empties into the air.
(a) What is the pressure within the ethanol in the first 4.70 cm
radius segment?
____ Pa
(b) How fast is the ethanol in the second 11.3 cm radius
segment?
___ m/s

The pressure of water flowing through a 6.3×10?2 ?m
-radius pipe at a speed of 1.1 m/s is 2.2 ×105 N/m2.
(a) What is the flow rate of water?
(b) What is the pressure in the water after it goes up a 4.6 ?m
-high hill and flows in a 5.0×10?2 ?m-radius pipe?

Water enters a basement Inlet pipe of radius 1.7 cm at 52 cm /
s. It flows through a pipe of radius 0.49 cm at a height of 36 m at
a gauge pressure 0.3 atm. What is the gauge pressure at the
basement? Give your answer to two decimal places and remember add
unit kPa after the numerical value.

The pressure of water flowing through a 5.9×10^-2 m-radius pipe
at a speed of 1.2 m/s is 2.2×10^5 N/m^2.
a) What is the flow rate of the water?
b) What is the pressure in the water after it goes up a 5.8
m-high hill and flows in a 4.2×10^-2 m-radius pipe?

Water is flowing into a factory in a horizontal pipe with a
radius of 0.0163 m at ground level. This pipe is then connected to
another horizontal pipe with a radius of 0.0380 m on a floor of the
factory that is 11.6 m higher. The connection is made with a
vertical section of pipe and an expansion joint. Determine the
volume flow rate that will keep the pressure in the two horizontal
pipes the same.
_________ m3/s

Water flowing at 40 L/s through a 9 cm diameter pipe transitions
to a 3 cm diameter pipe.
What is the water pressure difference between the pipes?
By what factor does the speed of the water increase moving from
the larger to smaller pipe?

Water is flowing into a factory in a horizontal pipe with a
radius of 0.0183 m at ground level. This pipe is then connected to
another horizontal pipe with a radius of 0.0300 m on a floor of the
factory that is 11.6 m higher. The connection is made with a
vertical section of pipe and an expansion joint. Determine the
volume flow rate that will keep the pressure in the two horizontal
pipes the same.
