Desalination & Membrane Water Treatment Equipment worked example

Leak Test Capacity at 99% expected test-stand uptime: a worked example in desalination & membrane water treatment equipment

Push expected test-stand uptime up to 99% and the picture changes. This example computes every intermediate figure at that operating point. Use it when leak test capacity in desalination and membrane water treatment equipment is being asked to take on more work and you need to know if there is room.

The inputs for this scenario

  • Assemblies tested per leak-test cycle: 4 assemblies / cycle (unchanged)
  • Leak-test cycles available in the period: 480 cycles (unchanged)
  • Expected test-stand uptime: 99 % (raised for this scenario; the documented default is 90)
  • First-pass leak-test yield: 97 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross leak-test capacity = assemblies tested per cycle × available leak-test cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,844 units for forecast passed leak-test capacity, the number this scenario is built around.
  • At this operating point the engine returns 1,920 units for gross leak-test capacity.
  • At this operating point the engine returns 19.2 units for leak-test uptime capacity loss.
  • At this operating point the engine returns 57.02 units for leak-test rework capacity loss.

How this compares with the baseline

  • Against the tool's baseline example, where expected test-stand uptime sits at 90% and the headline result is 1,676 units, this scenario comes in 10% above the baseline at 1,844 units.
  • It computes forecast passed leak-test capacity by multiplying assemblies-per-cycle and available cycles into gross capacity, then derating for test-stand uptime and first-pass yield. 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

  • Forecast passed leak-test capacity: 1,844 units (headline result)
  • Gross leak-test capacity: 1,920 units
  • Leak-test uptime capacity loss: 19.2 units
  • Leak-test rework capacity loss: 57.02 units
