The inner unit of a SY type static mixer consists of cross bars, which are 45 degrees along the axis of the tube. The mixed effect of SY type is between SV type and SK type, which can disperse the droplets to 2-5um during the differentiation process, and it can be used for a mixing process. The non-uniformity coefficient of a X X - 2 is less than 1% amplification effect.
The
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)
