8.1.11.2 About the Graph
The fluid graph visually illustrates some of the important qualities of the fluids
shown.
Temperature Range: The temperature scale is shown in degrees Celsius. A
sense of the fluid's general range of application is indicated. Qualities including
pour point, freeze point, important viscosity points, flash point, boiling point and
others may be shown.
Freezing Point: The freezing point of a fluid is an obvious limitation to stirring. As
the freezing point is approached high viscosity may also limit good stirring.
Pour Point: The pour point represents a handling limit for the fluid.
Viscosity: Points shown are at 50 and 10 centistokes. Greater than 50 centi-
stokes stirring is very poor and unsatisfactory for bath applications. At 10
centistokes and below optimum stirring can occur. These are rules of thumb
which have been useful for most applications.
