Incompressible flow and incompressible fluid
WebFor incompressible flows where density is constant, mass conservation dictates that the velocity of the fluid is inversely proportional to the cross-sectional area of the nozzle. This means that as the cross-sectional area of the nozzle decreases, the velocity of the fluid increases. If we further assume that the viscosity of the fluid is ... WebA flow is said to be incompressible if the density of a fluid element does not change during its motion. It is a property of the flow and not of the fluid. The rate of change of density of a material fluid element is given by the material derivative. Hence the flow is incompressible if the divergence of the velocity field is identically zero.
