📐 LPRO Hydrodynamics (Crossflow Velocity 0.2 m/s, Concentration Polarization Beta <1.15)

LPRO Membrane Crossflow & Polarization Calculator

Model boundary layer mass transfer and concentration polarization factor ($eta = exp(J / k) < 1.15$) across high-permeability polyamide RO sheets: maintain optimal crossflow feed velocities ($v_{cross} ge 0.20 ext{ m/s}$), prevent mineral supersaturation at membrane surfaces, and membrane life yields.
