Head losses are a result of wall friction in all types of pipelines and of local resistance to flow, for example in valves and fittings (see also Pressure loss). Recommended flow velocitiesFor cold water: Suction line 0.7-1.5 m/s Discharge line 1.0-2.0 m/sFor hot water: Suction line 0.5-1.0 m/s Discharge line 1.5-3.5 m/s Head loss in a pipe The equation for the head loss of a flow in a Puhui Pipe manufacturer in China
