Empirical models are now used for predicting the performance of hydrocyclones in terms of capacity, cut size (d50,c), water split and partition curve. These models (such as the model by Lynch and Rao and the model by Plitt) were developed and checked for hydrocyclones with diameters larger than 4 in. However, for smaller-diameter hydrocyclones, little empirical modeling has been done.
