14.2.2. Examining Deflection and Pressure in Structures

Try these first

1. 1.

   What does the Reynolds number help determine in fluid flow?

   Hint

   Think about flow types associated with different flow speeds.

2. 2.

   Define viscosity in your own words.

   Hint

   Consider how thick or thin a fluid is!

3. 3.

   What does the Reynolds number indicate in fluid flow?

   • Viscosity
   • Flow type
   • Surface tension

   Hint

   Relate it to how smoothly the fluid flows.

4. 4.

   True or False: The Froude number is defined as the ratio of inertial forces to viscous forces.

   • True
   • False

   Hint

   Think about which forces are being compared.

5. 5.

   Analyze a spillway with a known Froude number of 3.5. Discuss the implications of this number on the design and flow behavior.

   Hint

   Consider how rapid water flow and gravitational impact shape the design.

6. 6.

   Propose a design for measuring the viscosity of an unknown fluid sample and how it could affect the flow rate in a controlled environment.

   Hint

   Think about how viscosity changes with temperature and how that affects flow.
