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?

## Solutions

##### Expert Solution

Assuming liquid to be incompressible and hence applying

continuity equation . at each

cross-section.

Where A is cross-section area and V is flow speed
