Planning calculator: PET air-recovery comparison
Enter measured or explicitly assumed values. Keep the units and measurement boundary consistent. Compare a second scenario before choosing equipment.
Equation and scope
1000A ÷ B; 1000C ÷ D; (1000A ÷ B) − (1000C ÷ D)
- A: Before: Measured energy [kWh]
- B: Before: Good bottles [Quantity]
- C: After: Measured energy [kWh]
- D: After: Good bottles [Quantity]
⌈x⌉ rounds upward and ⌊x⌋ downward to a whole count. min/max select the lowest/highest sample. ∉ means outside the stated interval.
Compare measured energy per thousand good bottles before and after a change. A reduction is meaningful only when bottle, preform, quality, operating window and meter boundary are comparable. No supplier savings percentage is assumed.
Worked example: editable assumptions
Record assumptions separately from measurements. The example numbers demonstrate arithmetic and are not a recommended equipment specification.

Calculation stays in this browser; this worksheet sends no project inputs to the server.
Before procurement, ask the responsible specialist to review the assumptions, drawings and test evidence. A valid calculation does not mean a project has passed acceptance.
Can lower total energy still mean higher energy per good bottle?
These are invented teaching inputs, not equipment ratings, market prices or an accepted tolerance. The two scenarios change one assumption while holding the other inputs constant. Use the comparison to identify what must be measured or agreed for your project.
Read both inputs and outputs in the stated units. The input register explains what evidence to request before substituting your own values. If a source is missing, record the uncertainty rather than silently entering zero or accepting a supplier estimate as a measurement.

| Reduction | % | 25 | -12.5 |
What the comparison means
The after-change energy total remains lower, but the second scenario reduces its good-bottle denominator. The specific energy comparison can therefore reverse direction. Report both energy and accepted output rather than advertising a lower meter reading alone. These invented windows illustrate normalization; they do not establish any air-recovery saving on an actual line.
How to establish this input
| Record item | How to establish this input |
|---|---|
| Before: Measured energy | Keep meter start and finish readings, the measurement period, metered equipment boundary and accepted output record. Include enough information to distinguish a change in consumption from a change in product mix, rejects or running time. |
| Before: Good bottles | Keep the physical count or usable-stock record for the stated configuration and time. Identify incomplete, blocked, rejected or unavailable stock separately. A total installed capacity is not automatically the quantity available in the comparison. |
| After: Measured energy | Keep meter start and finish readings, the measurement period, metered equipment boundary and accepted output record. Include enough information to distinguish a change in consumption from a change in product mix, rejects or running time. |
| After: Good bottles | Keep the physical count or usable-stock record for the stated configuration and time. Identify incomplete, blocked, rejected or unavailable stock separately. A total installed capacity is not automatically the quantity available in the comparison. |
Evidence to request
Keep meter start and end readings, accepted bottle counts, product format, reject disposition and comparable production windows. Investigate changed operating conditions before attributing a difference to one equipment feature.
Project decision record
| Record item | Project decision record |
|---|---|
| Input assumptions | Identify the bottle, pack or material configuration, operating mode and measurement boundary. State the start and finish of the observation and which accepted output the comparison represents; unlike boundaries cannot establish a performance improvement. |
| How to establish this input | Mark every input as measured, taken from a drawing, quoted or assumed. Retain the source document identifier, revision, date and responsible person. The same numeral with a different unit or data status is not automatically a comparable input. |
| Project decision record | Ask the responsible supplier and buyer to agree actual acceptance criteria and the evidence that will demonstrate them. Teaching values and calculated outputs on this page do not become approved operating settings or contractual performance guarantees. |
| Evidence to request | Record the decision affected by the result, the measurement or trial still needed, its owner and the next review. Keep unresolved items visible in the handover file instead of changing the figures to make a preferred equipment option appear acceptable. |
Why can lower total electricity use fail to demonstrate air-recovery savings?
The before-and-after totals must be divided by their own accepted bottle counts. A smaller meter total can simply represent less production. Use the same meter boundary and comparable operating periods, and retain both the absolute specific-use difference and its percentage basis instead of comparing only one headline number.
Which inputs should you verify before using this result?
These are hypothetical sensitivity examples, not measurements from a factory. The lower and higher inputs are chosen for teaching; they are not equipment limits, approved settings, uncertainty intervals or recommended allowances. Whole-count and bounded inputs are adjusted to keep the examples valid, so the changes are not all the same percentage.
Read one input row at a time. For its lower and higher result, only that named input changes; every other input remains at the baseline shown in the first table. Do not combine all the lower columns or all the higher columns into a single operating scenario: those combined conditions have not been calculated here.

| Before: Measured energy | kWh | 76.8 | 96 | 115.2 |

Interpret this problem
A one-input comparison isolates the arithmetic effect inside this model. It does not establish that the input can change independently on a real line. If two quantities share the same measurement, production period or physical constraint, ask the responsible supplier to review that relationship before changing the project basis.
Equal displayed results need interpretation. Whole-item outputs can remain unchanged until a rounding boundary is crossed; displayed decimal values can also hide a small change. Check the stated unit, the underlying counts and the specific explanation below before concluding that an input has no effect.
What to verify next
Use a surprising difference to choose the next measurement, rather than selecting whichever assumption gives the preferred answer. Record the input label and unit, its measured or assumed status, document revision, operating condition and who will verify it. Keep the original record so a later reader can reproduce the comparison.
For a supplier discussion, take the baseline, one changed input, the affected output and the unresolved question together. Agree the field observation or controlled trial that can resolve it and record the responsible person. A mathematical change does not by itself approve equipment capacity, quality acceptance, installation or a purchase decision.
Where do the inputs come from, and which result do they change?
Mark each project value as measured, quoted, taken from a drawing, assumed or awaiting confirmation. Early estimates can use stated assumptions; a missing value is not zero. The calculator defaults are illustrative, not evidence about your plant.
| Input or result / Unit | Evidence to request | Substitution to avoid |
|---|---|---|
| Before: Measured energy (kWh) | Retain the before-period meter identifier, start and finish readings, observation times and included consumers. Identify setup, idle and production energy within that window. | A before-period bill or whole-building meter may include unrelated loads. Keep the electrical boundary consistent with the after-period comparison. |
| Before: Good bottles (Quantity) | Record accepted bottles for exactly the before-energy measurement period. Identify the counter location and treatment of rejects, samples and bottles already in the line. | Do not divide before-period energy by a nominal nameplate count or by the after-period production quantity. Those substitutions change the specific-energy denominator. |
| After: Measured energy (kWh) | Retain the after-period meter readings and times using the same included equipment as the before case. Document any other operating or equipment changes. | A meter reset, different boundary or shorter window can mimic a saving. Keep the raw readings rather than only a reported percentage improvement. |
| After: Good bottles (Quantity) | Reconcile the after-period accepted count with the same start and finish times used for after-energy measurement. Preserve the relevant reject and stock movements. | More filled bottles is not necessarily more accepted output. Changing the counting point between periods can distort the normalized comparison even with correct meter readings. |

Applies when: (Before: Measured energy > 0)
ceil rounds up to a whole count; floor rounds down. min and max select the smallest and largest values. I(P) is 1 when condition P is true, otherwise 0; ∨ means “or”. π is the circle constant. Semicolons separate function arguments.
These relations explain the planning model. A mathematical result does not set acceptance limits, approve a machine setting or establish legal filling tolerances. Keep project approval and evidence separate from arithmetic.
After: Measured energy + After: Good bottles: What happens when two planning inputs change together?
Compare four explicitly hypothetical combinations. Only the two named inputs vary; every other input remains fixed. These examples complete the corner cases around the single-input comparisons above. They are teaching assumptions, not measured plant data, recommended settings, approved limits or probability ranges.
Read A as lower/lower, B as lower/higher, C as higher/lower and D as higher/higher, in the displayed input order. A is the comparison origin, not the original project baseline. The two factors are varied independently for this calculation; that does not prove every combination is physically feasible.
Keep the reference case fixed and read the sign. A negative saving means an increase under these assumptions; higher total consumption can coexist with lower consumption per accepted unit.

The last difference is D − C − B + A, in the output unit. Zero means the four computed values are additive at these selected points; it does not prove independence in a real line. A nonzero difference can follow from multiplication, division or whole-count rounding. It is not a measured machine interaction or a statistical confidence interval.
A direct difference between two percentage results is expressed in percentage points, not as a relative percentage change.
