WebDarcy–Weisbach equation. 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. WebPlane Poiseuille flow is flow created between two infinitely long parallel plates, separated by a distance h with a constant pressure gradient G = − d p d x is applied in the direction of flow. The flow is essentially unidirectional because of infinite length.
