Gypsum Slurry Usage at 98% slurry transfer efficiency: a worked example
This scenario runs the gypsum slurry usage calculation on the strong side: 98% slurry transfer efficiency, with every other input held at its documented default. Use it when setting a stucco purchase order or mixer batch size before a board line run to avoid shorting the slurry distributor mid-run.
The inputs for this scenario
- Boards to produce: 500 boards (unchanged)
- Stucco dosage per board: 0.08 lb / board (unchanged)
- Slurry transfer efficiency: 98 % (raised for this scenario; the documented default is 85)
Working through the calculation
- Applying the documented formula (Theoretical slurry = boards to produce x stucco 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 slurry transfer 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.
- Use it when planning a batch, sizing a mixer charge, or reconciling silo consumption against boards produced. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
Results at a glance
- Required quantity: 40.82 lb (headline result)
