2 cards from this section. Quick, good the night before a test.
Define local acceleration in your own words.
Think of how a single point in a flow changes speed.
What is convective acceleration and how is it different from local acceleration?
Consider motion through different speed areas.
What defines local acceleration?
Reflect on how speed changes with time at fixed points.
True or False: Convective acceleration is solely dependent on time changes.
Consider the movement of fluid particles across different areas.
Given the velocity profile V(x,y,z) = (3y^2 - z, -2x + z, 5x + 4y), calculate the local and convective acceleration at the point (2, 1, 3).
Use partial derivatives with respect to each spatial component.
A fluid flows through a pipe with varying cross-sections. Explain how local and convective acceleration would change when moving from a wide section to a narrow section.
Think about how velocity must adapt as forced through a smaller area.
