Abstract
Concepts originally introduced in 1970 (1), concerning the rotational “viscosity vectors”, are further developed: as is the concept of “effective molecular mass” (for viscosity). This is used first to calculate “molar” viscosities at three temperatures for a sucrose concentration of 60% in water. These differ from published experimental values by about 1%.
Adjustments of the “effective” molecular mass to give agreement at all concentrations up to 60%, are made on a geometrical empirical basis.
A tentative viscosity-concentration table is presented for 20°, 25° and 37°C., for concentrations of 20, 40 and 60% w/w.
Finally, a few significant plasma and whole-blood viscosity-values are chosen to illustrate how the field of clinical results can be mapped against an aqueous-sucrose background.
