In fluid dynamics, the Darcy–Weisbach equation is an empirical equation that relates the head loss, or pressure loss, due to friction along a given length of pipe to the average velocity of the fluid flow for an incompressible fluid. The equation is named after Henry Darcy and Julius Weisbach.

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 with the flow velocity. An equivalent statement that implies incompressibility is that the divergence of … See more The fundamental requirement for incompressible flow is that the density, $${\displaystyle \rho }$$, is constant within a small element volume, dV, which moves at the flow velocity u. Mathematically, this … See more As defined earlier, an incompressible (isochoric) flow is the one in which $${\displaystyle \nabla \cdot \mathbf {u} =0.\,}$$ This is equivalent to … See more The stringent nature of the incompressible flow equations means that specific mathematical techniques have been devised to solve … 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.
