Question

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?

Answer #1

A 1.0 cm diameter pipe widens to 6.0 cm, then narrows to 0.3 cm.
Liquid flows through the first segment at a speed of 4.0 m/s.
(a) What is the speed in the second and third segments?
second segment =
m/s
third segment =
m/s
(b) What is the volume flow rate through the pipe?
(m3/s)

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?

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?

A 6.3 cm diameter horizontal pipe gradually narrows to 4.5 cm .
When water flows through this pipe at a certain rate, the gauge
pressure in these two sections is 31.0 kPa and 26.0 kPa ,
respectively. What is the volume rate of flow?

A 7.8 cm diameter horizontal pipe gradually narrows to 6.8 cm .
When water flows through this pipe at a certain rate, the gauge
pressure in these two sections is 33.0 kPa and 22.6 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 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.

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.
