2 cards from this section. Quick, good the night before a test.
Define pressure force.
Think about how fluid pushes against surfaces.
What do viscous forces depend on?
Consider how different fluids flow.
What type of force acts perpendicular to a fluid's surface?
Think about how fluids push against surfaces they encounter.
True or False: Viscous forces help in increasing the flow velocity of fluids.
Remember how thicker fluids behave compared to thinner ones.
A pipe has water flowing at three distinct sections, creating various pressure and viscous forces. Calculate how changes in these forces affect the velocity at each section.
Use Bernoulli's equation as a starting point.
In a river, how would the introduction of a dam affect both pressure forces upstream and viscous forces downstream? Analyze the implications on flow behavior.
Think about how hydraulic pressure changes with elevation and flow restrictions.
