📏 Gravity Motive Head (Hydrostatic Liquid Column Motive Head Delta-P = rho*g*H, Zero kW)

Gravity Thermosyphon Motive Head Calculator

Calculate hydrostatic liquid head ($Delta P = ho_{liq} g Delta H$) generated by vertical separation ($H = 1.5 ext{ to }4.0 ext{ meters}$) between server cold plates and elevated overhead condensers: overcome total two-phase piping frictional resistance naturally without electric motors, and PUE savings.
