2 cards from this section. Quick, good the night before a test.
Define conservation of momentum.
Think about how forces affect motion.
What is a control volume in fluid mechanics?
Consider it as a box around fluid flow.
What does conservation of momentum help us predict?
Think about what momentum affects.
True or False: Steady flow indicates that all properties of a fluid in motion are changing over time.
Consider what 'steady' implies.
A pipe has two exits. At the first exit, 5 m/s flows into a tank, while 10 m/s exits into another region. If the diameter at Exit 1 is 0.1 m and Exit 2 is 0.15 m, calculate the force acting on the pipe from these exits.
Utilize mass conservation equations alongside momentum flux principles.
For aircraft refueling at 568 liters/min with a specific gravity of 0.68, calculate the thrust needed to keep a constant velocity. Determine the momentum before and after refueling.
Boyle's Law could assist in relating pressure changes to thrust requirements.
