Question 1.
Define Friction Factor.
Show hintHide hint
Think about how it impacts flow in pipes.
Question 2.
What does Reynolds Number indicate?
Show hintHide hint
Consider the nature of fluid flow.
3Question 3.
What is the main purpose of the Darcy-Weisbach equation?
- To calculate flow rate
- To find pressure drop
- To determine viscosity
Show hintHide hint
Think about where the equation applies.
4Question 4.
True or False: The Colebrook equation is explicit in nature.
- True
- False
Show hintHide hint
Consider how the equation is set up.
Question 5.
A 100m long pipe with a roughness of 0.02mm carries water. After refurbishment, its roughness is reduced to 0.005mm. Calculate the change in head loss if the flow rate is constant.
Show hintHide hint
Consider both friction factors based on the new roughness.
Question 6.
For a 2m diameter pipe, if the flow is turbulent with Re around 100,000, how would adjusting the diameter affect the pressure drop?
Show hintHide hint
Reflect on the relationship between D, V, and Re.
