Lesson: Pressure Produced by Fluids
In this lesson, we will learn how to use the formula p = ρgh to calculate the pressure produced at different depths by different fluids that gravity acts on.

Which of the following formulas correctly shows the relationship between the pressure exerted by a fluid, the height of the fluid above the point at which pressure is measured, the density of the fluid, and the gravitational acceleration rate ?
The hull of a sunken boat, laying on the seabed, is 12 m below the surface of the sea, where the sea water has an average density of kg/m3. The hull’s surface area is 15 m2. What is the total force exerted by seawater on the hull?
In a well, a 0.35 m high bucket full to the brim with water of density kg/m3 is supported by a rope. The bucket is dropped into the well and its fall is slowed by the tension in the rope. During the bucket’s fall, the pressure on its base is 2 310 Pa. At what rate does the bucket accelerate down the well?
