How to use the horizontal cylindrical tank volume calculator
Find liquid volume in a horizontal cylindrical tank by fill depth. Enter radius, length, liquid depth in the fields above; the liquid volume, liquid volume, percent full are computed instantly and plotted on the chart so you can see how the answer changes.
Formula
Variables
- r — Radius (m)
- L — Length (m)
- d — Liquid depth (m)
Worked example
With radius = 1 m, length = 4 m, liquid depth = 0.8 m, the calculator gives liquid volume ≈ 4.693917 m³; liquid volume ≈ 4,693.917 L; percent full ≈ 37.353 %.
Frequently asked questions
What is the formula for the horizontal cylindrical tank volume calculation?
Liquid volume (m³) = L × (r × r × acos((r-d) / r)-(r-d) × √(2 × r × d-d × d)). Liquid volume (L) = [Liquid volume] × 1000. Percent full (%) = 100 × [Liquid volume] / (π × r × r × L). Here r is radius (m), L is length (m), d is liquid depth (m).
What inputs do I need for the horizontal cylindrical tank volume calculator?
You need radius in m, length in m, liquid depth in m. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use this calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
