Pressure differences can be created in various ways, such as removing air from one region (e.g., drinking through a straw) or maintaining a height of fluid (e.g., water towers). For an incompressible fluid, the rate at which matter enters a fluid-filled tube open at both ends must equal the rate at which fluid exits the tube. This conservation of mass is described by the continuity equation (A1v1 = A2v2).
