WebThe loss coefficient is derived as a function of the ratio of lateral to total flow rate. An energy transfer process from the main channel flow to the lateral inflow or vice versa, which is … WebHenri Philibert Gaspard Darcy (1805–1858) was a French civil engineer. He performed numerous experiments of flow resistance in pipes ( Darcy 1858) and in open channels (Darcy and Bazin 1865 ), and of seepage flow in porous media ( Darcy 1856). He gave his name to the Darcy-Weisbach friction factor and to the Darcy law in porous media.
