Powder Transfer Efficiency at 54% target transfer efficiency: a worked example

Suppose target transfer efficiency falls to 54%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate how much sprayed powder deposits on parts instead of becoming overspray.

The inputs for this scenario

  • Powder deposited on parts: 42 lb (held at the documented default)
  • Powder sprayed from guns: 60 lb (held at the documented default)
  • Target transfer efficiency: 54 % (the input this scenario stresses; the baseline uses 75)

Working through the calculation

  • The calculation starts from the formula this tool documents: Transfer efficiency = powder deposited on parts รท powder sprayed.
  • Rate works out to 70 % at these inputs, and this is the headline figure for the scenario.
  • Gap to target works out to -16 points at these inputs.
  • Affected count works out to 42 count at these inputs.
  • Total count works out to 60 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target transfer efficiency sits at 75% and the headline result is 70 %, this scenario lands almost exactly on the baseline at 70 %.
  • It computes transfer efficiency as powder deposited on parts divided by powder sprayed, plus the point gap to your target. 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.

Results at a glance

  • Rate: 70 % (headline result)
  • Gap to target: -16 points
  • Affected count: 42 count
  • Total count: 60 count

Run it with your numbers
