Question

Water flows through a horizontal pipe at a rate of 2.3 m3/s. A pressure gauge placed on a 40 cm diameter section of the pipe reads 210.3 kPa. What is the gauge pressure in a section of pipe where the diameter is constricted to 35 cm and what has caused this change in pressure?

Answer #1

Oil is flowing through a horizontal pipe
constriction. In the large section, the pipe has a diameter of 1.7
meters and a pressure of 500 kPa. If the pipe constricts to a
diameter of 0.5 meters, what is the pressure in the constricted
pipe section. (Assume the oil flow rate is 65 m3/min
and oil density is 900 kg/m3)
49,432.419 kPa
13.096115 kPa
486.403885 kPa
513.801133 kPa
2. Oil is flowing through a
horizontal pipe expansion. In the small section,...

A 7.0-cm-diameter horizontal pipe gradually narrows to 5.0 cm .
When water flows through this pipe at a certain rate, the gauge
pressure in these two sections is 33.0 kPa and 23.0 kPa ,
respectively.
What is the volume rate of flow?

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.
