Fluids in Motion
Every second, 1.20 m3 of water enters a heating system through a pipe of medium width, A,
with a cross-sectional area of 0.200 m2. The water then flows into a wide pipe, B, with an
area of 0.600 m2, and flows out through a narrow pipe, C, with an area of 0.100 m2.
1. What is the flow rate in each pipe?
______________________________________________________________
2. What is the length of the segment of pipe A that contains 1.20 m3 of water? Sketch the
marks on the diagram above showing the segments of pipes B and C that would contain
the same amount of water. What is the length of each segment?
______________________________________________________________
3. How much time is required for water to travel the lengths you found in pipe A? in pipe B?
in pipe C?
______________________________________________________________
4. What is the flow speed of water in each pipe?
______________________________________________________________
5. Does the speed of water increase when it enters a narrow pipe? Does the flow rate
increase? Explain.
