What happens to pressure as you dive deeper into a pool?
Think about the weight of water above you.
What is gauge pressure?
What do you compare gauge pressure against?
What is the formula for calculating pressure at a certain depth in fluid?
Look for a formula that combines atmospheric pressure and hydrostatic pressure.
True or False: Pressure is greater at the bottom of a lake than at the surface.
Consider the concept of weight and how it affects pressure.
A submarine is at a depth of 300 meters in seawater. Calculate the gauge pressure on its walls, knowing the density of seawater is 1025 kg/m^3.
Use the gauge pressure formula.
