Invented water draws
Record measured draws by hand on the water sheet.
Hot-water register steps
- Write each draw volume in whole millilitres.
- Record occurrences using the same observation window.
- Add draw volumes before converting to daily litres.
Invented water draws
| Hot-water register entry | Units | Hot-water register value |
|---|---|---|
| Measured draws 1: Draw volume | mL | 10000 |
| Measured draws 1: Daily uses | whole uses/day | 2 |
| Measured draws 2: Draw volume | mL | 5000 |
| Measured draws 2: Daily uses | whole uses/day | 1 |
| Record days | days | 30 |
| Volume unit | mL | mL |
| Hot-water register entry | Units | Hot-water register value |
|---|---|---|
| Daily Ml | mL/day (shown as L/day) | 25.000 L/day |
| Period Ml | mL (shown as L) | 750.000 L |
| Mean Draw Ml | mL/use (shown as L/use) | 8.333 L/use |
Volume calculation
- daily_mL = sum(volume_mL * uses).
- period_mL = daily_mL * record_days.
- mean_draw_mL = daily_mL / sum(uses), rounded half-up to whole mL. Litres display exactly three decimal places.
Hot-water register limits
- Measured draws: from 1 through 20 draws
- Draw volume: 1–1000000 mL
- Daily uses: 0–100 whole uses/day
- Record days: a period of 1 to 366 days
- Missing draw figures: volume withheld.
Draw-record basis
- Measured draws belong to one household over the same chosen period.
- Enter the requested units yourself; no conversion or price lookup is supplied.
- Sample draws are fictional and are not usage recommendations.
