Flow Rate Formula. Flow rate is the measure of the volume of liquid that moves in a certain amount of time. Moreover, the flow rate depends upon the channel from which the liquid is passing or the area of the pipe, and the velocity of the liquid. Besides, the formula is Fluid flow rate = area of the pipe or channel × velocity of the liquid. Q = Av

In this model, which is based on the first principles, the pressure (P(r)) through the radial distance, r, of a centrifuge can be predicted by the following equation: s r b r b which is known as Zeitsch model. The sign rb. is the radial distance to the base of the filter cake.
Feed flow rate. With the increase in the feed flow rate, the separation efficiency and the split ratio increase slower and slower, whereas the pressure drop increases faster and faster. Then feed flow rate levels out over the operating range of hydrocyclones. Because further increase in feed flow rate will lead to an unacceptable high pressure ...

In terms of the entropy production rate in rotor and volute region, the difference isn't so distinct. The entropy production rate in volute region is 1.77 × 10 − 4 W / K while the entropy production rate in rotor region is 1.1 × 10 − 4 W / K. It's evident that the volute region experiences the majority of flow loss.

They proposed a detailed CFD solution to entropy production, which explains the local entropy formation …
Therefore, the flow evolution along a speed line is analysed by performing unsteady, three-dimensional flow simulations using a centrifugal compressor geometry with ported shroud. A stable operating condition, at high mass-flow rates, is compared to lower mass-flow rate operating conditions close to and at surge.
