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

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.
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.
