Ref. 13.
2) Ref. 14.
3) Ref. 18, 22, 23.
4) Ref. 21.
5) Ref. 28.
6) The absolute accuracy of viscosity measurements is very hard to evaluate.
The best guide is probably the deviation plot in Figure 12.2.
7) To convert Pa-s or kg/m-s to P,
multiply by 107, to convert from m2/s to cm2/s, multiply by
104
