WebJan 21, 2024 · The continuity equation is very fundamental. It is a kind of "nothing gets lost theorem". Let us define the total charge $ Q(t) = \int_V d^3x \rho(t,x)$. Using the continuity equation you can prove that the total charge is conserved - you … WebA simplified derivation and explanation of the continuity equation, along with 2 examples.
WebJul 17, 2024 · Material derivative. The Navier-Stokes equation is derived from applying Newton’s law \(F=m a\) to a fluid flow. We first consider the acceleration of a fluid element. The velocity of the fluid at a fixed position \(x\) is given by \(\mathbf{u}(\mathbf{x}, t)\), but the fluid element is not at a fixed position but follows the fluid in motion.Now a general … WebThis is expressed in the Continuity Equation: Where: Q = the volumetric flow rate. A = the cross sectional area of flow. V = the mean velocity. Calculation of flow rate is often complicated by the interdependence between flow rate and friction loss. Each affects the other and often these problems need to be solved iteratively.
