Centrifugation in a Hydrocyclone: Oper. Conds Tab (Based on B. Diam. & Dim. Anal.)

HydrocycloningOperCondsForDimAnalysis.jpg

This tab appears on the interface dialog of the Hydrocycloning operation (see Centrifugation in a Hydrocyclone) when the options to size the equipment based on body diameter and dimensionless analysis are selected through the Equipment tab of the Hydrocyclone that hosts this operation (see Hydrocyclone: Equipment Tab).

Variable Definitions, Ranges and Default Values

The following table shows a brief description of the variables appearing in this tab. The table also displays their default values and their generally acceptable range:

Variable

Default Value

Range

 

○ Liquid Viscosity (Pa-s)
The viscosity of the liquid phase of the feed stream (which consists of the liquid/solid amount of all pure components that are not set to be removed on the Mat. Balance tab).

0.001

Positive

○ Reduced 50% Cut Size (micron)
The particle size for which the reduced grade efficiency is 50%.

10.0

Positive

● Pressure Drop (Pa)
The pressure drop of each hydrocyclone.

0.0

Positive

● Operating Throughput (per Unit) (m3/h)
The volumetric liquid/solid flow rate of the feed stream divided by the number of units.

0.0

Zero or Positive

○ Power Type
Indicates the power type that is used by the operation. Click on the list box to bring up a list of available power types in order to select one.

<Std Power>

Any Power Type

○ (Power Consumption) Efficiency
The ratio of ideal to actual power consumption by this operation (for pumping, etc.).

100.0

(0, 100]

● Power (kW)
The total power consumption for the entire operation (i.e., for all equipment units).

0.0

Positive

○ Power Dissipation to Heat (%)
The percentage of total power consumed for this operation that turns into heat, thereby raising the temperature of the material contained in the equipment.

100.0

[0,100]

Symbol Key: ○ User-specified value (always input); ● Calculated value (always output); ◙ Sometimes input, sometimes output
