Mixing, Blending & Industrial Batch Processing worked example

Viscosity Adjustment at 65% process correction factor: a worked example in mixing, blending & industrial batch processing

Suppose process correction factor falls to 65%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Compare a current batch viscosity reading to the target spec and apply a process correction factor to plan thinner or thickener addition.

The inputs for this scenario

  • Current batch viscosity: 1,450 cP (held at the documented default)
  • Target viscosity: 1,200 cP (held at the documented default)
  • Process correction factor: 65 % (the input this scenario stresses; the baseline uses 90)

Working through the calculation

  • The calculation starts from the formula this tool documents: Viscosity ratio = current batch viscosity รท target viscosity.
  • Effective throughput works out to 0.79 ratio at these inputs, and this is the headline figure for the scenario.
  • Raw throughput works out to 1.21 ratio at these inputs.
  • Efficiency works out to 65 % at these inputs.
  • Runtime works out to 1,200 hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where process correction factor sits at 90% and the headline result is 1.09 ratio, this scenario comes in 27.78% below the baseline at 0.79 ratio.
  • It divides current batch viscosity by target viscosity to get a raw ratio, then multiplies by a process correction factor to give an adjusted, condition-corrected ratio. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
