3 cards from this section. Quick, good the night before a test.
Define velocity distribution as it applies to fluid dynamics.
Think about how flow speed changes in a nozzle.
What is steady flow?
Consider what happens to the flow when conditions remain unchanged.
What is the formula to calculate acceleration in fluid flow?
Recall the definition of acceleration in the context of fluid mechanics.
True or False: In a steady flow, local acceleration is typically non-zero.
Think about the implications of 'steady' in fluid dynamics.
If a fluid passes through a nozzle, entering at 15 ft/s and exiting at 35 ft/s, compute the average acceleration if the time taken was 2 seconds. How does this relate to the principles of continuity?
Remember how velocity and area are interconnected in continuous flow systems.
Given a reducing diameter nozzle with inlet diameter D1 = 4 inches and outlet diameter D2 = 2 inches, if the fluid enters at a velocity of 20 ft/s, calculate the exit velocity.
Ensure you remember the area calculation for circular sections.
