Pressure Drop InformationHousing pressure drop using fluid with 0.9 S.G.
Housing pressure drop is directly proportional to specific gravity.
Element Pressure Drop
Multiply actual flow rate times factor in table below to determine pressure drop with fluid at 32 cSt (150 SUS), 0.9 S.G. Correct for other fluids by multiplying new viscosity in cSt/32 (SUS/150) x new S.G./0.9.
