WebNov 8, 2024 · Because we are dealing with an incompressible fluid that has fixed density, there is a simple relation between the velocity of the fluid and the cross-sectional area of the pipe. Figure 5.3.3 depicts a segment of a pipe where it becomes wider. Figure 5.3.3: Fluid Flow in a Non-uniform Pipe.
In fluid dynamics, a flow is considered incompressible if the divergence of the flow velocity is zero. However, related formulations can sometimes be used, depending on the flow system being modelled. Some versions are described below: Incompressible flow: $${\displaystyle {\nabla \cdot \mathbf {u} =0}}$$. This can … See more In fluid mechanics or more generally continuum mechanics, incompressible flow (isochoric flow) refers to a flow in which the material density is constant within a fluid parcel—an infinitesimal volume that moves … See more In some fields, a measure of the incompressibility of a flow is the change in density as a result of the pressure variations.
