Vaw is the kinematic viscosity of distilled water at 
the same temperature. 
x is the square root of the salinity 
A, B, C are empirical constants (Table 33) 
The values of o in the extreme right hand column of 
Table 32 give a measure of agreement between Equation 24 
and the experimental data where

In doing this, the values of viscosity for sample 
number 5 were not used, as they seemed to be too far from 
the curve along which the rest of the data lay. Values of 
viscosity at even values of salinity were calculated (Eq. 1 
of (18)). These values were fit by least squares against 
the temperature using 
' 
log; )v = A‘ + eee ae (26) 
Ci (G5) 
where T is the absolute temperature and A', B', C' are 
empirical constants. 
The viscosities at 10 and 0°C are obtained as described 
in the section on distilled water results. The values of 
o given in the bottom row of Table 32 were similarly defined. 
The viscosity values at the same temperature and salinity 
were also calculated by fitting the data against the 
temperature first and then the salinity but the results 
were the same to within 0.0001. For comparison, Tables 34- 
41 give the original viscosity data.
