Chapter 9, Problem 5SP
A pipe with a circular cross-section has a diameter of 9 cm. It narrows at one point to a diameter of 5.2 cm. The pipe is carrying a steady stream of water that completely fills the pipe and is moving with a speed of 1.6 m/s in the wider portion.
- a. What are the cross-sectional areas of the wide and narrow portions of the pipe? (A = πr2, and the radius is half the diameter.)
- b. What is the speed of the water in the narrow portion of the pipe?
- c. Is the pressure in the narrow portion of the pipe greater than, less than, or equal to the pressure in the wider portion? Explain.
