3 cards from this section. Quick, good the night before a test.
What is meant by equilibrium conditions in fluid mechanics?
Think about the concept of balance.
Define surface tension.
Consider why raindrops form spherical shapes.
In equilibrium conditions, what must be true about the forces acting on a fluid?
Think about how balance works.
True or False: Surface tension is a dominant force in large-diameter tubes.
Consider the effects of surface area.
Given a capillary tube of diameter 2 mm, calculate the height the water will rise if the surface tension is 0.072 N/m and the density of water is 1000 kg/m³.
Focus on calculating the effective radius from the diameter.
If a tube has a contact angle of 30 degrees with water, how would this angle affect the height of rise compared to a 0 degree angle in practical applications?
Consider how angles influence capillarity in real-life scenarios.
