P1 H ΔP VP
P1 = Tank Pressure, psia H = Liquid Height, ft ΔP = Pressure Loss to Friction, psi VP = Vapor Pressure, psia PSI x 2.31 = feet H2O
NPSHa = P1 x 2.31 + H ‐ ΔP x 2.31 ‐ VP x 2.31

Plan Take inventory – know what needs to be cleaned Establish acceptance criteria – write a URS Regulatory Clean in a Reproducible and Effective manner Flow Rates/Paths Find a path to every pipe, component and equipment Hydraulics Calculate pressure drops Remember NPSH requirements for pumps Utilities/ Infrastructure Purified water and WFI consumption rates establish size(s) for CIP tank(s) Operations Valves vs. flow panels / swing elbows Equipment setup / COP Validation Acceptance criteria from URS
