All pipe assemblies were filled with water and pressurized up to 300 psi/20 bar, which exceeds typical operating pressures of HVAC systems. 783 + 10 –2. The friction factor will be dependant on the pipe size, inner roughness of the pipe, flow velocity and fluid viscosity. But before I do, I forgot to mention something during the discussion on suction lines that also applies to liquid lines. The first stage involves sizing your duct work for adequate vol-ume (CFM) and velocity (ft/m) for the type of dust you will be handling. Since chillers are in series, pump flows are already. Two related but distinct concerns emerge when designing a fluid flow system: sizing the pipe and determining the flow-pressure relationship.
