Question 1.
What is the formula to calculate head loss due to sudden enlargement?
Show hintHide hint
Recall the components of the formula.
Question 2.
What value is generally assumed for K_entrance if not given?
Show hintHide hint
Think about the common configurations of pipe entries.
3Question 3.
What formula is used to calculate head loss in sudden enlargement?
- h_L = K_E * (V_1^2)/(2g)
- h_L = K_L * (V_1^2)/(2g)
- h_L = K_B * (V_1^2)/(2g)
Show hintHide hint
Recall the type of enlargement being discussed.
4Question 4.
True or False: The head loss coefficient K_exit is generally 0.
- True
- False
Show hintHide hint
Think about the implications of what happens at a pipe exit.
Question 5.
A water system has a sudden enlargement from 5 cm to 15 cm, and water flows at 4 m/s in the smaller pipe. Calculate the head loss using appropriate coefficients.
Show hintHide hint
Focus on proper area calculations.
Question 6.
For a steady pipe system with a gradual expansion leading to reduced head losses, calculate the head loss if the initial velocity is 5 m/s and you have K_E = 0.8.
Show hintHide hint
Pay attention to velocity changes between points!
