Freezing Point: The freezing point of a fluid is an obvious limitation to stir-
ring. As the freezing point is approached high viscosity may also limit
performance.
Pour Point: This represents a handling limit for the fluid.
Viscosity: Points shown are at 50 and 10 centistokes viscosity. When viscosity
is greater than 50 centistokes stirring is very poor and the fluid is unsatisfactory
for bath applications. Optimum stirring generally occurs at 10 centistokes and
below.
