Question 1.
What is the formula for calculating head loss due to sudden enlargement?
Show hintHide hint
Remember the role of the loss coefficient.
Question 2.
What is the default value of K_entrance if unspecified?
Show hintHide hint
This is a common value used in calculations.
3Question 3.
What is the primary factor affecting head loss in a pipe network?
- Friction
- Temperature
- Pressure
Show hintHide hint
Think about the physical interactions between fluid and pipe walls.
4Question 4.
True or False: All energy is lost during sudden expansions when K_L approaches 1.
- True
- False
Show hintHide hint
Reflect on the loss coefficients in sudden expansions.
Question 5.
Calculate the total head loss in a pipeline that has a major loss of 4m and encounters 3 fittings each causing a minor loss of 0.5m each. What is the total head loss?
Show hintHide hint
Sum major and minor losses to find the total.
Question 6.
For a conical diffuser with V1 = 5 m/s and V2 = 2 m/s, calculate head loss if KL is known to be 0.8. What is h?
Show hintHide hint
Note the velocities change in calculation for dynamic flow.
