Question 1.
What is velocity defect?
Show hintHide hint
Think about changes in flow speed.
Question 2.
Describe minor losses in pipe systems.
Show hintHide hint
Consider what happens when flow changes direction.
3Question 3.
What does the velocity defect indicate?
- Friction loss
- Difference in velocity
- Pipe diameter
Show hintHide hint
Consider what is meant by 'defect' in the context of flow.
4Question 4.
True or False: Minor losses only occur due to friction.
- True
- False
Show hintHide hint
Think of what other components influence flow.
Question 5.
A horizontal pipe of diameter D1 flows water at a steady rate. If you were to connect a parallel pipe of diameter D2 (D2<D1), calculate the velocity in each pipe given that the discharge remains constant.
Show hintHide hint
Apply the principle of continuity correctly for both paths.
Question 6.
Two parallel pipes have differing friction factors (f1 and f2). If both pipes have to maintain the same flow rate, calculate the head loss across each pipe using the Darcy-Weisbach equation.
Show hintHide hint
Consider how discrepancies in f affect the energy balance.
