Coatings, Inks & Specialty Chemical Production worked example

Viscosity Adjustment at 65% viscosity adjustment uptime: a worked example in coatings, inks & specialty chemical production

This worked example runs the viscosity adjustment numbers for a tougher week than the baseline: 65% viscosity adjustment uptime instead of the typical 90%. Estimate usable adjusted product output after viscosity-adjustment cycles, uptime, and first-pass release yield.

The inputs for this scenario

  • Adjusted volume per correction cycle: 350 gal / cycle (held at the documented default)
  • Available viscosity correction cycles: 6 cycles (held at the documented default)
  • Viscosity adjustment uptime: 65 % (the input this scenario stresses; the baseline uses 90)
  • First-pass viscosity release yield: 96 % (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Gross viscosity adjustment = adjusted volume per correction cycle × available viscosity correction cycles.
  • usable viscosity adjustment works out to 1,310 gal at these inputs, and this is the headline figure for the scenario.
  • gross viscosity adjustment works out to 2,100 gal at these inputs.
  • viscosity adjustment lost to downtime works out to 735 gal at these inputs.
  • viscosity adjustment lost to yield works out to 54.6 gal at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where viscosity adjustment uptime sits at 90% and the headline result is 1,814 gal, this scenario comes in 27.78% below the baseline at 1,310 gal.
  • Use it when planning viscosity-correction capacity, evaluating a station's effective output, or quantifying losses from downtime versus rejected re-reads. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • usable viscosity adjustment: 1,310 gal (headline result)
  • gross viscosity adjustment: 2,100 gal
  • viscosity adjustment lost to downtime: 735 gal
  • viscosity adjustment lost to yield: 54.6 gal
