Time-temperature conversion viscosity correlations

This provides time-temperature-conversion-viscoslty correlations which can be directly utilized in computer studies designed to minimize actual molding times while avoiding a damaging exotherm during cure. The particular system studied is a low viscosity liquid epoxy cured with aminoethylpiperazine and was found to be moldable over specific temperature ranges. 

Water Droplet Size. To find a solution to the settling equation (i.e., for either equation 1 or 2), the water droplet size, d, must be known. Qualitatively, the water droplet size is expected to increase with an increase in retention time in the coalescing section and with heat input. Conversely, it should decrease with increase in the oil-phase viscosity. Furthermore, viscosity will have a greater effect on coalescence than temperature. Practical experience in the design of treaters has resulted in a reliable correlation of water droplet size to oil-phase viscosity (3) ... 

The most common way to use ANN modeling is direct modeling, when output variables are correlated with inputs of the network. For instance, in the batch bulk free radical polymerization of methyl methacrylate, using (a,a -azobis(isobutyronitrile) as initiator, monomer conversion, polymerization degrees, and reaction viscosity are related to the working conditions (temperature, initial concentrations of reactants, and initiator and time) (Figiue 12.3a).
