3 cards from this section. Quick, good the night before a test.
Define major head loss.
Think about where friction occurs in a long fluid movement.
What is the purpose of the Darcy-Weisbach equation?
Recall that it involves pipe length and diameter.
What does major head loss result from?
Think about where energy is lost in long distances.
True or False: Minor head losses can be ignored in long pipelines where friction is the main component.
Recall your examples of fittings and valves.
You have a pipeline that runs 1000 meters with a diameter of 0.2 meter. It's carrying fluid at 3 m/s, with a friction factor of 0.01. Determine the major head loss and its impact on the pressure at the end of the pipeline.
Be careful to convert the units properly!
In a system where the entrance loss coefficient is 0.5, exit loss is negligible, and we've established major head loss is 10m. What total head loss needs compensating to maintain a discharge rate of 20L/s?
Involve Bernoulli's equation to see discharge relationships!
