WebOct 31, 2024 · V 1 = flow velocity at the inlet of the pipe (m/s) V 2 = flow velocity upstream of the orifice plate (m/s) For incompressible fluids (usually the case for liquids), the density remains constant during fluid flow. Therefore, the conservation of mass equation becomes: Where: A 1 = cross-section area of the pipe downstream of the orifice plate (m 2) WebOct 7, 2016 · Unidirectional Flushing. UDF isolates each pipeline to create flow in a single direction to quickly and efficiently clean the pipe. By concentrating flow, UDF creates higher velocities that are better able to clean the pipe. The cleaned mains may have improved water clarity or color, reduced turbidity and improved chlorine residual.
