3 cards from this section. Quick, good the night before a test.
What happens to fluid pressure as depth increases?
Think about the weight of the fluid above.
What is the SI unit of pressure?
It's named after a scientist.
What is the relationship between depth and pressure in fluids?
Think about what happens if you go underwater.
True or False: The pressure in a fluid acts only in one direction.
Consider what happens underwater.
You have a tank filled with oil (density = 900 kg/m³) and water (density = 1000 kg/m³). If the height of oil is 5m and water is 2m, what is the pressure at the bottom of the tank? (Assume g = 9.81 m/s²)
Don't forget to calculate pressure contributions from both liquids!
A submarine operates at a depth of 300 m in saltwater (density approx 1025 kg/m³). Calculate the pressure it endures.
Use the formula we discussed earlier and remember to add atmospheric pressure!
