🚰 CDU Hydraulics (Dual Redundant VFD Pumps, Primary FCW Delta-P <10 PSI)

Data Center CDU Primary to Secondary Hydraulics Calculator

Model hydraulic flow and pressure drops across facility water (primary FCW) and computer room cold water (secondary TLC) loops: optimize dual-redundant high-efficiency stainless centrifugal pumps ($P_{pump} < 15 ext{ kW}$ @ $600 ext{ GPM}$), maintain secondary pressure at $25 ext{ PSIG}$, and PUE yields.
