Question 1.
What is the static head?
Show hintHide hint
Think about the height difference.
Question 2.
What formula do you use to calculate fluid velocity?
Show hintHide hint
Recall the variables defined in previous discussions.
3Question 3.
What is the main purpose of calculating head loss in a pump system?
- A. To determine pump power requirements
- B. To measure flow rate
- C. To reduce system efficiency
- D. No purpose
Show hintHide hint
Think about why head loss is relevant to pumping systems.
4Question 4.
True or False: Major losses in a pipe network are caused by fittings.
- True
- False
Show hintHide hint
Consider the definitions we discussed for both major and minor losses.
Question 5.
A pump must lift water 20 meters at a flow rate of 15 L/s. Calculate the power required considering a head loss of 5 meters. Then analyze how varying the friction factor from 0.02 to 0.04 affects the power needed.
Show hintHide hint
Consider the relationship between head loss, flow rate, and pump power.
Question 6.
In a network where two pipes (6cm and 12cm in diameter) are connected, water flows at a rate of 30 L/s. Determine the flow in each pipe and how much head loss occurs with a friction factor of 0.018 for the first pipe and 0.02 for the second. How would the flow rate change if the system experienced a sudden pressure drop?
Show hintHide hint
Use conservation of mass principles to determine how flow divides between the two pipes.
