Review Fluid: Anything that fows / takes the shape o± its container. m = ρ V Density: Mass per unit volume Pressure: Force per unit area F = pA The pressure at a point in a fuid in static equilibrium depends on the depth o± that point but not on any horizontal dimension o± the fuid or its container. At a given level, the pressure is the same in all directions. p = p 0 + gh Pascal’s Principle: A change in the pressure applied to an enclosed incompressible fuid is transmitted undiminished to every portion o± the fuid and the walls o± its container.
