A 1.0-cm-diameter pipe widens to 2.0 cm, then narrows to 0.50 cm. Liquid flows through the first segment at a speed of 4.0 m/s. What are the speeds in the second and third segments? What is the volume flow rate through the pipe? If all three parts of the pipe are at the same height and the pressure in the first segment is recorded at 80 kPa, what is the pressure in the second and third segments of the pipe?

6 Question 5: Flow through a Sudden Expansion and Sudden Contraction Pipe 1, a smaller diameter pipe, is connected to a larger diameter pipe, Pipe 2; the connection between the two pipes is abrupt or sudden. Section 1 is located on the smaller diameter Pipe 1 and Section 2 is located on the larger diameter Pipe 2. Both Sections 1 and 2 are located sufficiently far away from the sudden pipe join that any locally generated flow disturbance has negligible...

Water flows at speed of 6 m/s through a horizontal pipe of
diameter 3.5 cm. The gauge pressure P1 of the water in the pipe is
1.7 atm. A short segment of the pipe is constricted to a smaller
diameter of 2.4 cm .
