WebReuse of wastewater has been widespread in this era to support the water sustainability process. Therefore, treated wastewater should be conveyed to suitable places and adopted for different uses. This study presents an empirical relationship between WebThe hydraulic diameter is used the Darcy-Weisbach equation to calculate pressure loss in ducts or pipes. Note! - the hydraulic diameter is not the same as the geometrical equivalent diameter of non-circular ducts or pipes. Hydraulic diameter can be calculated with the generic equation dh = 4 A / p (1) where dh = hydraulic diameter (m, ft)
