Evaporation Loss with starting batch liquid volume of 2,500 gal: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop starting batch liquid volume to 2,500 gal, then walk the calculation through step by step. Estimate remaining liquid after evaporation, vent loss, and handling loss are deducted.

The inputs for this scenario

  • Starting batch liquid volume: 2,500 gal (the input this scenario stresses; the baseline uses 5,000)
  • Evaporation loss during processing: 180 gal (held at the documented default)
  • Vent and purge liquid loss: 35 gal (held at the documented default)
  • Transfer and handling loss: 60 gal (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Remaining liquid = starting liquid volume - evaporation, vent, and handling losses.
  • remaining process liquid works out to 2,225 gal at these inputs, and this is the headline figure for the scenario.
  • total liquid losses works out to 275 value at these inputs.
  • starting liquid volume works out to 2,500 value at these inputs.
  • remaining liquid percent works out to 89 % at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where starting batch liquid volume sits at 5,000 gal and the headline result is 4,725 gal, this scenario comes in 52.91% below the baseline at 2,225 gal.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to starting batch liquid volume, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It treats each loss as a flat known volume, so it will not model temperature-, humidity-, or time-dependent evaporation rates or vapor that recondenses back into the batch.
