1. Pressure at the inlet of the Hydrocyclone can tell you a lot. Pressure at the inlet of the Hydrocyclone is an important indicator of where the separation point (also called cut point or d50) will be. The separation point is the size at which a particle has a 50-50 chance of reporting either to the underflow or overflow.

centrifugal clarification, a process that runs in hydrocyclones and sedimentation centrifuges. Centrifugal clarification is highly effective as it speeds up the sedimentation of impurities by a factor of 3 to 30 [2]. Hydrocyclones are different from centrifuges or centrifugal separators in the sense that they lack moving or rotary parts.

Hydrocyclone performance. As demonstrated in Fig. 8 all tests were performed at hydrocyclone efficiencies lower than 60%. One explanation for the low efficiency is probably a sub-optimal hydrocyclone design. An optimal inlet diameter is according to Young et al. (1994) Di = 0.25 Dc, where Dc is the cyclone diameter.
