Tank Working Volume at 98% usable fill level below overflow: a worked example
What does the result look like when usable fill level below overflow reaches 98%? The full calculation is worked below with real intermediate numbers. checking whether a vessel has enough working volume for a batch, heel, headspace, or transfer plan
The inputs for this scenario
- Inside diameter or wall-to-wall width: 96 in (unchanged)
- Straight-side (wetted) height: 144 in (unchanged)
- Cubic-inch to gallon conversion factor: 0 gal / in3 (unchanged)
- Usable fill level below overflow: 98 % (raised for this scenario; the documented default is 85)
Working through the calculation
- Applying the documented formula (Working volume = inside dimension × wetted dimension × conversion factor × usable fill level) to the inputs above produces each figure below.
- At this operating point the engine returns 4,606 gal for usable tank working volume, the number this scenario is built around.
- At this operating point the engine returns 47 gal for geometric tank volume.
- At this operating point the engine returns 98 x for usable fill level.
- At this operating point the engine returns 13,824 in2 for tank cross section factor.
How this compares with the baseline
- Against the tool's baseline example, where usable fill level below overflow sits at 85% and the headline result is 3,995 gal, this scenario comes in 15.29% above the baseline at 4,606 gal.
- A figure at this level is achievable when usable fill level below overflow is genuinely sustained, not just peaked for a shift. It treats the tank as a straight prism and ignores dished heads, cones, coils, baffles, and dead volume below the outlet, so it is an operating estimate rather than a certified strap-chart figure.
