Let us consider an infinitesimal volume The Continuity Equation Over the last few classes, we have derived the first of the basic conservation laws of fluid dynamics, the momentum equation, in both its three This leads us to the continuity equation for compressible ﬂows: ∂ρ ∂t + ∂(ρ· u) ∂x + ∂(ρ· v) ∂y + ∂(ρ· w) ∂z =() For an incompressible ﬂuid, this simpliﬁes to ∂u ∂x + ∂v ∂y The Continuity Equation: Conservation of Mass for a Fluid Element which is the same concluded in (4). s is conserved;F m t +. Consider a jet of water turned through a horizontal angle. x-equation: ∑ Fx = Fx = ∫ ρ ud V + ∫ ρ u V ⋅ dA dt CS. F = ∑ ρ u V ⋅ A steady flow. The average speed of blood through the capillaries is ~ 5× m.s Calculate the effective cross sectional area of the capillaries and Jet deflected by a plate or vane. It is evident that in a certain region of space the matter entering it must be equal to the matter leaving it. convergence (more mass coming in than going out) or divergence (more mass going out than coming in) of. The radius of the aorta is ~mm and the blood flowing through it has a speed ~ mm.s A capillary has a radius ~ 4× mm but there are literally billions of them. These equations speak physics. The derived equation is mass conservation for any ﬂow (compressible continuity equation. In low speed ﬂow, a similar computation shows that any velocity ﬁeld speciﬁed via ψ(x,y) will automatically satisfy ∇·V~ =which is the constant Equation () is called the continuity equation and is the general partial differen-tial equation for conservation of mass for any moving, continuous medium (continuum). nergy equations. The continuum might be a compressible gas, a liquid or a moving solid such as glacier ice or the rock crust of the EarthI NCOMPRESSIBLE FLOW Blood flowing through our body. V =This is the mass divergence or flux form of the continuity. mass into out of the volume equation which says that the mass in a volume can only change locally (Eulerian frame) through the flux. CV and CS are jet so that Fx and Fy are vane reactions forces fluid. x CS. = ρ Vx (− VA 1) + ρ Vx (VA 2) continuity equation Chapterid DynamicsJ.D. The equation of continuity. They are the mathematical statements of three fun-damental physical princ. the continuity, momentum and. Easy 488
