Chapter 12, Problem 12.38E

Water is flowing in a pipe with a varying cross-sectional area, and at all points the water completely fills the pipe. At point 1 the cross-sectional area of the pipe is 0.070 m², and the magnitude of the fluid velocity is 3.50 m/s. (a) What is the fluid speed at points in the pipe where the cross-sectional area is (a) 0.105 m² and (b) 0.047 m²? (c) Calculate the volume of water discharged from the open end of the pipe in 1.00 hour.
