3 cards from this section. Quick, good the night before a test.
Define viscosity in your own words.
Think of fluids like water and honey.
What is the equation for bulk modulus?
Consider how pressure and volume are related.
What happens to viscosity as fluid temperature increases?
Consider how heating changes fluid movement.
True or False: Bulk modulus only applies to liquids.
Think about the properties of compressible materials.
A fluid has a bulk modulus of 2500 kPa. If the pressure is increased by 500 kPa, what is the expected change in volume for a fluid with an initial volume of 1 m3?
Rearranging the formula will help find the change in volume.
Given a surface tension of 0.072 N/m for water, calculate the pressure difference inside a bubble of radius 1 mm. Is the pressure inside higher or lower?
Recall the formula for pressure difference due to surface tension.
