Continuity Equation
Fluids: Continuity Equation As we may have already learned, a liquid is a nearly incompressible fluid, and if compression is present in a given situation, such compression is effectively negligible. On the other hand, gas can be compressed and should be appropriately accounted for. This difference in compression makes liquid a lot preferable compared to gas as we can easily neglect compression. Hence, the reason why most entry-level problems involving pressure only include liquids. The Continuity Equation is somewhat different from Archimedes' and Pascal's Principles since it deals with fluid in motion or fluid dynamics, while the previous ones deal with fluid in a static or hydrostatic environment. However, for the Continuity Equation to make sense, the involved fluid must have a Laminar Flow . This means that the fluid we're working on must be free-moving or must have no viscosity nor friction. Volume Flow Rate Before I present the Continuity
