Question 1.
What does the Reynolds number indicate?
Show hintHide hint
Think about how fluid behavior changes with speed.
Question 2.
Identify the mathematical relationship derived from Nikuradse’s experiments regarding roughness.
Show hintHide hint
Consider how surface texture relates to fluid dynamics.
3Question 3.
What does the behavior of turbulent flow depend on?
- Reynolds Number
- Temperature
- Viscosity
Show hintHide hint
Recall its application in predicting laminar vs turbulent flow.
4Question 4.
True or False: In turbulent flow, velocity is consistent across a cross-section.
- True
- False
Show hintHide hint
Consider the implications of chaotic flow behavior.
Question 5.
Consider a pipe of diameter 0.2 m with a turbulent flow whose Reynolds number is 3000. Calculate the expected velocity profile near a rough section of the pipe.
Show hintHide hint
Employ the derived equations discussed during the lecture to guide your calculations.
Question 6.
Evaluate how slight variations in roughness height can influence flow velocity in a rough-surfaced pipe with a known discharge rate. Find the impact of doubling the roughness height on flow characteristics.
Show hintHide hint
Focus on how friction loss is calculated in relation to roughness.
