Kinematic viscosity in SSU versus dynamic or absolute viscosity can be expressed asī = 4.632 for temperature 100 o F (37.8 o C)ī = 4.664 for temperature 210 o F (98.9 o C) μ = dynamic or absolute viscosity (cP) SG = Specific Gravity ν centiStokes = kinematic viscosity (centiStokes)ĭegree Engler is used in Great Britain as a scale to measure kinematic viscosity. Saybolt Universal Seconds is also called the SSU number (Seconds Saybolt Universal) or SSF number (Saybolt Seconds Furol). This method has largely been replaced by the kinematic viscosity method. The efflux time is Saybolt Universal Seconds ( SUS ) required for 60 milliliters of a petroleum product to flow through the calibrated orifice of a Saybolt Universal viscometer - under a carefully controlled temperature and as prescribed by test method ASTM D 88. Saybolt Universal Seconds (or SUS ) is an alternative unit for measuring viscosity. Other Viscosity Units Saybolt Universal Seconds (or SUS, SSU ) This is a free app that can be used offline on mobile devices. Related Mobile Apps from The Engineering ToolBox
