WebSep 12, 2024 · The rate at which the charges flow past a location—that is, the amount of charge per unit time—is known as the electrical current. When charges flow through a … The fundamental requirement for incompressible flow is that the density, , is constant within a small element volume, dV, which moves at the flow velocity u. Mathematically, this constraint implies that the material derivative (discussed below) of the density must vanish to ensure incompressible flow. Before introducing this constraint, we must apply the conservation of mass to generate the necessary relations. The mass is calculated by a volume integral of the density, :
