In fluid dynamics, the Darcy–Weisbach equation is an empirical equation, which 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.
7) According to Darcy's formula, the loss of head due to friction in the pipe is (where f = Darcy's coefficient, l= Length of pipe, v= Velocity of liquid in pipe, and d=Diameter of pipe)
