The interior of the SX type static mixer unit consisting of cross stripes, stripes and the axis of the tube shell 45 °.SX type hybrid effect between the SV and SK type, when used for emulsifying process can make the droplets dispersed to 2 to 5 microns, used in the mixing process of general not uniformity coefficient, amplification effect is not big.SX type static mixer < pressure drop calculation is based on the hydraulic diameter of the benchmark, and considering the influence of the void fraction of the coefficient of friction。
SX type pressure drop calculation formula
△P=(f*ρc/ε2W2)*L/dh Re=dh*ρc*w/μ*ε
W=(Q/πD2*900)*10^6 1Kg（f）/cm2=98100N/m2
dh=（πD2L-4Aδ）/(2A+πDL)
△PFriction coefficient （N/m2） f friction coefficient (dimensionless) ρc fluid density（Kg/m3）
WFluid linear velocity（m/s） Lmixer length（mm） dhHydraulic diameter（mm）
εVoid fraction (non-dimensional) μfluid viscosity（CP） A hybrid unit area（mm2）
δUnit material thickness（mm） pipe diamete（mm） Reynolds number (dimensionless)
