Starch/Additive Usage at 98% metering efficiency: a worked example
Push metering efficiency up to 98% and the picture changes. This example computes every intermediate figure at that operating point. Use it before a production run to set the additive batch size and avoid a process upset caused by the metering system running dry mid-run.
The inputs for this scenario
- Boards to produce: 500 boards (unchanged)
- Additive dosage per board: 0.08 lb / board (unchanged)
- Metering efficiency: 98 % (raised for this scenario; the documented default is 85)
Working through the calculation
- Applying the documented formula (Theoretical additive = boards to produce x additive dosage per board) to the inputs above produces each figure below.
- At this operating point the engine returns 40.82 lb for required quantity, the number this scenario is built around.
- At this operating point the engine returns 40 lb for theoretical amount.
- At this operating point the engine returns 0.82 lb for loss allowance.
- At this operating point the engine returns 98 % for efficiency.
How this compares with the baseline
- Against the tool's baseline example, where metering efficiency sits at 85% and the headline result is 47.06 lb, this scenario comes in 13.27% below the baseline at 40.82 lb.
- It computes the pounds of additive required for a run by dividing the theoretical dose (boards times dosage per board) by metering efficiency. 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.
