Plating, Anodizing & Surface Treatment worked example

Rinse Water Usage with rinse water usage use rate of 30 units / hr: a worked example in plating, anodizing & surface treatment

Push rinse water usage use rate up to 30 units / hr and the picture changes. This example computes every intermediate figure at that operating point. Use it when rinse water usage in plating, anodizing and surface treatment is being quoted and consumables are a real chunk of the cost stack.

The inputs for this scenario

  • Rinse water usage use rate: 30 units / hr (raised for this scenario; the documented default is 12)
  • Rinse water usage runtime: 8 hr (unchanged)
  • Rinse water usage unit cost: 3.5 $ / unit (unchanged)

Working through the calculation

  • Applying the documented formula (Rinse water usage consumed = rinse water usage use rate × rinse water usage runtime) to the inputs above produces each figure below.
  • At this operating point the engine returns 240 units for rinse water usage consumed, the number this scenario is built around.
  • At this operating point the engine returns 840 $ for rinse water usage run cost.
  • At this operating point the engine returns 8 hr for rinse water usage runtime.
  • At this operating point the engine returns 3.5 $ / unit for rinse water usage unit cost.

How this compares with the baseline

  • Against the tool's baseline example, where rinse water usage use rate sits at 12 units / hr and the headline result is 96 units, this scenario comes in 150% above the baseline at 240 units.
  • It multiplies your rinse water flow rate by runtime to get total water consumed, then multiplies that volume by unit cost to get the run cost. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Rinse water usage consumed: 240 units (headline result)
