Context & Assumptions

Clean-in-Place (CIP) is a maintenance procedure used to remove foulants from membrane surfaces in RO and NF systems. This calculation ensures the cleaning fluid reaches a turbulent Reynolds number to provide sufficient shear stress without exceeding mechanical velocity limits.
