Question

A 6.4 cm diameter horizontal pipe gradually narrows to 3.9 cm . When water flows through this pipe at a certain rate, the gauge pressure in these two sections is 30.5 kPa and 25.2 kPa , respectively.

What is the volume rate of flow?

Express your answer to two significant figures and include the appropriate units.

Answer #1

A 7.2 cm diameter horizontal pipe gradually narrows to 4.8 cm .
When water flows through this pipe at a certain rate, the gauge
pressure in these two sections is 33.0 kPa and 26.0 kPa ,
respectively.
What is the volume rate of flow?
Express your answer to two significant figures and include the
appropriate units.

A 7.0-cm-diameter horizontal pipe gradually narrows to 4.0 cm .
When water flows through this pipe at a certain rate, the gauge
pressure in these two sections is 32.0 kPa and 24.0 kPa ,
respectively.
What is the volume rate of flow? Express your answer using two
significant figures.

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 32.0 kPa and 25.0 kPa ,
respectively.
What is the volume rate of flow?
Express your answer using two significant figures.

pressure in these two sections is 31.0 kPa and 26.0 kPa ,
respectively. What is the volume rate of flow?

A 6.7 cm diameter horizontal pipe gradually narrows to 5.3 cm .
When water flows through this pipe at a certain rate, the gauge
pressure in these two sections is 31.5 kPa and 23.4 kPa ,
respectively.What is the volume rate of flow?

A 6.8 cm diameter pipe gradually narrows to 4.0 cm. When water
flows through this pipe at a certain rate, the gauge pressure in
these two sections is 33.0 kPa and 24.0 kPa, respectively. What is
the volume rate of flow?

A 6.6 cm diameter pipe gradually narrows to 4.0 cm. When water
flows through this pipe at a certain rate, the gauge pressure in
these two sections is 30.0 kPa and 24.0 kPa, respectively. What is
the volume rate of flow?

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?

A 1cm diameter pipe widens to 2 cm then narrows to 0.5 cm.
Liquid flows through the first segment at a speed of 4 m/s.
a- what are the speeds in the second and third segments?
b- what is the volume flow rate through the pipe?
