Lesson 3 - Hydrostatic Eqn, Manometer, Buoyancy

Purpose of a manometer and how to read it

• measure differences in pressure

• side of manometer w/ higher height = lower pressure

Relationship between pressure and altitude

• higher in altitude = lower in pressure

• deeper in pool = higher pressure

What is buoyancy?

force exerted by the fluid on the object

What is Archimedes’ Principle?

buoyant force on body = weight of fluid displaced by that body

ΔF = W
