🚰 Riser Hydraulics (300-ft Rooftop Chilled Riser, Pumping Head Loss <15 PSID)

Split CDU Long-Distance Piping Hydraulics Calculator

Model friction head losses, static vertical lift, and thermal insulation heat gain across long-distance header piping ($200 ext{ to }500 ext{ ft}$) connecting indoor server rooms to rooftop dry coolers: optimize pipe diameter ($4 ext{" to }8 ext{" 304SS}$) maintaining loop delta pressure $<15 ext{ PSID}$, and pumping power savings.
