Formula and assumptions
How this calculation works.
Track tank volume through entered intervals with measured inflow and outflow, separating overflow and unmet draw volume. Geometric ledger only. Enter compatible net rates, not a pump or drainage design.
A worked example
Illustrative inputs only. Product properties and design dimensions are not recommendations for your project.
- Geometric tank capacity
- 10 m³
- Initial contained volume
- 5 m³
- Interval duration
- 2 hours
- Measured inflow volume per hour
- 4 m³
- Measured outflow volume per hour
- 0 m³
- Interval duration
- 3 hours
- Measured inflow volume per hour
- 0 m³
- Measured outflow volume per hour
- 4 m³
Contained volume at the end: 0 m³
Rates are constant within each interval and use the displayed volume unit per hour. No pump performance, pressure, water quality or operating limit is assessed.
Before you purchase
Use dimensions from your plan and properties from your chosen product. Any design spacing, section or fixing pattern must already be specified.
