Industrial Cleaning, Washing & Parts Cleanliness worked example

Rinse Water Usage with rinse water flow rate of 210 gal / hr: a worked example in industrial cleaning, washing & parts cleanliness

This worked example runs the rinse water usage numbers for a tougher week than the baseline: rinse water flow rate of 210 gal / hr instead of the typical 420 gal / hr. Estimate rinse water consumption and cost from rinse flow, operating time, and water cost.

The inputs for this scenario

  • Rinse water flow rate: 210 gal / hr (the input this scenario stresses; the baseline uses 420)
  • Rinse operating time: 8 hr (held at the documented default)
  • Water and treatment cost: 0.01 $ / gal (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Rinse water consumed = rinse water flow rate × rinse operating time.
  • Rinse water consumed works out to 1,680 gal at these inputs, and this is the headline figure for the scenario.
  • Rinse water run cost works out to 20.16 $ at these inputs.
  • Rinse operating time works out to 8 hr at these inputs.
  • Water and treatment cost works out to 0.01 $ / gal at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where rinse water flow rate sits at 420 gal / hr and the headline result is 3,360 gal, this scenario comes in 50% below the baseline at 1,680 gal.
  • Use it when auditing a parts-washer rinse stage, comparing overflow versus controlled rinsing, or building the water line item in a cleaning-cost-per-part estimate. 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

  • Rinse water consumed: 1,680 gal (headline result)
  • Rinse water run cost: 20.16 $
  • Rinse operating time: 8 hr
  • Water and treatment cost: 0.01 $ / gal
