THE NUMBERS, EXPLAINED
How to use this calculator.
Each zone needs a whole pad count each session. Clean pads return after the entered whole number of days; inventory covers that many daily sessions.
Start with your inputs
Enter pads used in each floor zone, cleaning sessions per day, wash return delay (days). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Pads used in each floor zone | 1,2,1 |
| Cleaning sessions per day | 1 |
| Wash return delay (days) | 2 |
A worked example
With the example inputs above, pads per session is 4. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Pads per session | 4 |
| Minimum circulating pads | 8 |
How this is calculated
Pads per session
Add pads assigned to each zone.
Minimum circulating pads
Multiply session requirement by sessions per day and days before return.
Symbols and units
- a
- Pads used in each floor zone
- b
- Cleaning sessions per day
- c
- Wash return delay (days)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions and limits
Each zone needs a whole pad count each session. Clean pads return after the entered whole number of days; inventory covers that many daily sessions.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Pads per session; Minimum circulating pads. The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Each zone needs a whole pad count each session. Clean pads return after the entered whole number of days; inventory covers that many daily sessions.
