SP5. 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 nar- row portions of the pipe? (A = ar", 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.

Ethanol is flowing in a pipe and at all points completely fills the pipe. At point A in the pipe the gauge pressure is p and the cross-sectional area of the pipe is 0.0500 m² . The other end of the pipe (point B) is open to the air, has cross-sectional area 0.0120 m2, and is at a vertical height of 9.00 m above point A. Part A What must the gauge pressure p be at A if the volume flow rate out of the pipe at point B is 0.0800 m /s? Express your answer with the appropriate units.
