Question 1.
State the Darcy Weisbach equation. What do its parameters represent?
Show hintHide hint
Identify each parameter in the context of pipe flow.
Question 2.
What types of losses are considered in fluid systems?
Show hintHide hint
Think about the components affecting flow energy.
3Question 3.
What is the primary factor contributing to major head loss in a pipe?
- Friction
- Gravity
- Momentum
Show hintHide hint
Think about forces opposing fluid flow.
4Question 4.
True or False: Minor losses are typically negligible compared to major losses.
- True
- False
Show hintHide hint
Consider scenarios with many fittings.
Question 5.
A reservoir system has two reservoirs with a height difference of 20m. If the connecting pipe is 400m long and has a diameter of 0.15m, calculate the flow rate, considering a friction factor of 0.025 and a minor loss coefficient of 1.5.
Show hintHide hint
Ensure you consider both major and minor losses before deriving the flow.
Question 6.
For a system with a total head loss of 50m, comprising 30m major head loss and 20m minor head loss, discuss how changes in pipe diameter would affect the head loss.
