Document Summary
Bernoulli"s equation - puts work and energy concepts into a form suitable for fluids - used to understand why fluids in connected containers tend to have the same surface levels and how fluids flow from one place to another. A given mass of fluid always occupies the same volume although its shape may change. Described mathematically by the equation of continuity. The amount of fluid entering a tube is equal to the amount leaving. Use the philosophy that identifying the forces acting on an object means one can predict the subsequent motion. Density and pressure instead of mass and force are used in concepts. An object floating or submerged in a fluid experiences an upward/ buoyant force. Only gravity and surrounding liquid affects the object. Since it remains at rest, force exerted by fluid balances the weight. Buoyant force b exerted by the surrounding fluid = weight of the fluid segment.
