4 cards from this section. Quick, good the night before a test.
Define velocity defect.
Think about how flow behaves in turbulent conditions.
What are major losses in a pipe system?
Consider what happens as fluid moves through a rough surface.
What is the formula that relates velocity defect to average velocity?
Think about the definitions of velocity.
True or False: Minor losses in a pipe system are related purely to friction.
No hint provided
Given a flow with a diameter of 0.5 meters, calculate the average velocity if the flow rate is 0.25 m³/s. Then, determine the head loss using the Darcy-Weisbach equation with an f value of 0.02.
You’ll need to recall how to find the area of a circle and apply the velocity to the head loss formula.
Imagine a tank system with one outlet pipe experiencing a 5 m head loss. If the diameter of the pipe changes along its length, calculate the flow rate using continuity and energy equations.
Integrating continuity with energy principles is key for this problem.
