TAILIEUCHUNG - Chapter 14 fluids

Densities of some common substances at standard | Fig. , Figure A simple device for measuring the pressure exerted by a fluid. Table , Fig. , Figure A parcel of fluid (darker region) in a larger volume of fluid is singled out. The net force exerted on the parcel of fluid must be zero because it is in equilibrium. Fig. , Figure The external forces acting on the cube of liquid are the gravitational force Fg and the buoyant force B. Under equilibrium conditions, B = Fg. Fig. , Active Figure (a) A totally submerged object that is less dense than the fluid in which it is submerged experiences a net upward force. (b) A totally submerged object that is denser than the fluid sinks. At the Active Figures link at , you can move the object to new positions as well as change the density of the object to see the results. Fig. , Active Figure An object floating on the surface of a fluid experiences two forces, the gravitational force Fg and
