5 cards from this section. Quick, good the night before a test.
Define viscosity and explain its significance in fluid mechanics.
Think about how honey flows vs. water.
What does the ideal gas law express?
Recall the equation PV = nRT.
What is the unit of viscosity?
It combines pressure and time units.
True or False: The bulk modulus increases as the temperature of a fluid increases.
Think about how fluids behave under heat and pressure.
A helium balloon is released at sea level. If it rises to 3000 meters where the temperature drops by 10 degrees Celsius, calculate the pressure change in the balloon if initially, it was 101.3 kPa.
Remember how temperature and pressure are interconnected in gas laws.
Calculate the surface tension force in a droplet with a radius of 0.2 mm. Given that the surface tension of water at room temperature is 0.072 N/m, find the pressure difference across the droplet's surface.
Focus on the relationship between surface tension and pressure difference in a droplet.
