Medicine.Viscosity can be of critical importance in medicine as fluids are introduced into the body intravenously. Blood viscosity is a major issue: blood that is too viscous can form dangerous internal clots, while blood that is too thin will not clot; this can lead to dangerous blood loss a...
Likewise, reporting viscosity for trending purposes without a reference to temperature is nonsensical. The temperature must be defined to interpret the viscosity reading. Typically, viscosity is reported at 40°C and/or 100°C or both if theviscosity indexis required. ...
