... regimes. The models predict the value of critical velocities in pipes via ML using accessible parameters as inputs, namely, sand concentration, pipe inclination, pipe size, liquid density, liquid viscosity, particle density, and particle size. First, these models are trained with a set of 1640 data points...

Additionally, the mechanics behind drag reduction have been understood and the effect of DRAs on the flow rate and pressure of pipelines once injected has been understood. Factors such as location of DRA injection, DRA type vs. %Dr, and DRA concentration have...

... ABSTRACT Predicting the efficiency of a DRA is still dependent on the use of models developed through field tests. Two forms of the model are widely used for liquid pipelines, one correlates Drag Reduction (DR) as a function of DRA concentration only, and the other correlates DR as a function...

The benefits of this approach to pump selection are magnified if this is included as part of a larger optimization problem which manipulates both flow rates and DRA concentrations as well. Methodologies for the larger problem are beyond...
