Specialty Films, Membranes & Barrier Materials worked example

Barrier Performance Test Load with barrier test rig connected electrical load of 30 kW: a worked example

Push barrier test rig connected electrical load up to 30 kW and the picture changes. This example computes every intermediate figure at that operating point. Use it when barrier performance test load in specialty films, membranes and barrier materials is being quoted and energy is a real chunk of the specialty films, membranes and barrier materials cost stack.

The inputs for this scenario

  • Barrier test rig connected electrical load: 30 kW (raised for this scenario; the documented default is 12)
  • Barrier performance test runtime: 8 hr (unchanged)
  • Blended electricity rate: 0.12 $ / kWh (unchanged)
  • Film samples tested during runtime: 1,000 units (unchanged)

Working through the calculation

  • Applying the documented formula (Total barrier performance test load energy cost = barrier performance test load connected load × barrier performance test load runtime × blended electricity rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 240 kWh for barrier performance test load energy used, the number this scenario is built around.
  • At this operating point the engine returns 28.8 $ for total barrier performance test load energy cost.
  • At this operating point the engine returns 0.03 $ / piece for energy cost per kwh.
  • At this operating point the engine returns 3.6 $ / hr for hourly barrier performance test load energy cost.

How this compares with the baseline

  • Against the tool's baseline example, where barrier test rig connected electrical load sits at 12 kW and the headline result is 96 kWh, this scenario comes in 150% above the baseline at 240 kWh.
  • It computes total test-load energy from connected load times runtime, multiplies by your electricity rate for total cost, and divides by samples tested for a per-sample 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

  • Barrier performance test load energy used: 240 kWh (headline result)
