Question 1
What is the Reynolds number threshold for laminar flow?
- Below 1000
- Below 2300
- Above 4000
💡 Hint: It's one of those key thresholds!
Question 2
True or False: Minor losses occur due to friction along the length of the pipe.
- True
- False
💡 Hint: Consider fittings like bends.

Challenge Problems
Push your limits with challenges.
Question 1
Given a pipe with a Reynolds number of 3500, determine whether the flow is laminar, turbulent, or transitional. Describe the implications of this in terms of energy losses.
💡 Hint: Look at the thresholds discussed for Reynolds numbers.
Question 2
A water flow system experiences higher energy losses at fittings. If minor losses due to bends are quantified to K=0.5, and the velocity is 2 m/s, calculate the head loss at a bend using the formula h = K * (v^2)/(2g).
💡 Hint: Break it down, substituting the values one at a time.
