Moisture Content Adjustment at 3.6% moisture content: a worked example

Suppose moisture content falls to 3.6%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Calculate the dry tonnage of mineral product from wet weight using incoming moisture percentage, so you can report production on a consistent dry basis for inventory, sales, and quality records.

The inputs for this scenario

  • Wet tonnage (as-received): 200 tons (held at the documented default)
  • Moisture content: 3.6 % (the input this scenario stresses; the baseline uses 5)
  • Moisture testing and handling cost: 0.5 $ / ton (held at the documented default)
  • Fixed lab or QC cost per period: 75 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Dry tonnage = wet tonnage x (1 - moisture content / 100).
  • Dry tonnage works out to 193 tons (dry) at these inputs, and this is the headline figure for the scenario.
  • Water removed works out to 7.2 tons at these inputs.
  • Moisture content works out to 3.6 % at these inputs.
  • Moisture adjustment cost works out to 175 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where moisture content sits at 5% and the headline result is 190 tons (dry), this scenario comes in 1.47% above the baseline at 193 tons (dry).
  • It computes dry tonnage from wet tonnage and moisture percent, the water removed, and the total moisture testing and lab cost. 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

  • Dry tonnage: 193 tons (dry) (headline result)
  • Water removed: 7.2 tons
  • Moisture content: 3.6 %
  • Moisture adjustment cost: 175 $
