WebBernoulli's Equation. Bernoulli's equation is a special case of the general energy equation that is probably the most widely-used tool for solving fluid flow problems. It provides an easy way to relate the elevation head, velocity head, and pressure head of a fluid. It is possible to modify Bernoulli's equation in a manner that accounts for head … WebA flow net is a graphical representation of two-dimensional steady-state groundwater flow through aquifers. ... These functions both satisfy the Laplace equation and the contour lines represent lines of constant head ... Darcy's law describes the flow of water through the flow net. Since the head drops are uniform by construction, ...

WebHydraulic Head. In general, the hydraulic head, or total head, is a measure of fluid’s potential at the measurement point. It can be used to determine a hydraulic gradient between two or more points. In fluid dynamics, the head is a concept that relates the energy in an incompressible fluid to the height of an equivalent static column of that ... WebHead equation.
