Cyclone Pressure Drop

Estimate hydrocyclone inlet pressure loss with caller-calibrated dynamic-head coefficient; no universal geometry correlation.

Description

A hydrocyclone pressure-loss estimate can be expressed as a calibrated multiple of slurry dynamic head.

A hydrocyclone pressure-loss estimate can be expressed as a calibrated multiple of slurry dynamic head. Inlet velocity enters quadratically, so its unit and measurement basis matter.^[1]

The tool returns predictedPressureDropPa. The computation uses supplied observations and parameters rather than acquiring measurements.

When to use Cyclone Pressure Drop

Use this for the following task: Estimate hydrocyclone inlet pressure loss with caller-calibrated dynamic-head coefficient; no universal geometry correlation. Prepare observations and calibration parameters on the same unit and reporting basis.

How to use Cyclone Pressure Drop and understand its results

Prepare the measured quantities and supplied model parameters. Match the units and align paired lists before calculating.
Enter slurryDensityKgPerM3, inletVelocityMPerSecond, calibratedLossCoefficient according to the field table, then run the tool.
Read predictedPressureDropPa. Use the calculation below to interpret the selected mean or the model’s signs, units and comparison flags.
Review the supplied assumptions and calibration before comparing or reporting the result.

Input field	Meaning	Value type and bounds	Requirement
slurryDensityKgPerM3	Slurry density kg per m3	number	Required
inletVelocityMPerSecond	Inlet velocity m per second	number	Required
calibratedLossCoefficient	Calibrated loss coefficient	number	Required

Use positive density with nonnegative velocity and loss coefficient. Return the calibrated pressure drop in pascals.

pressure drop Pa = 0.5×lossCoefficient×density kg/m³×velocity²

The symbols and boundary conditions refer to the supplied fields and the implementation described above.

Output field	Meaning	Value type
predictedPressureDropPa	Predicted pressure drop pa	number

Limitations and assumptions

The coefficient is supplied and must match the operating geometry and slurry. No universal cyclone correlation, pump selection or separation performance is inferred.

Numerical inputs must be finite. Input-shape and calculation checks do not establish measurement quality or the validity of a supplied calibration.

Alternative or Complementary methods

Choose Cyclone Efficiency when you need its operation: Audit fine-overflow and coarse-underflow recovery from size-class flows and cut flags; distinct from corrected d50. Choose Cyclone Cut Size D50 for the complementary operation: Remove supplied water bypass from measured increasing partition curve and linearly interpolate corrected d50 in size; no extrapolation.
