Horizontal Cylindrical Tank Contents Calculator

Calculate liquid volume in horizontal cylindrical tanks.

Engineering & Power

Horizontal Cylindrical Tank Contents Calculator estimates fill volume given liquid depth for horizontal cylinders, useful in fuel/water tank gauging and material delivery scheduling. It is useful for logistics, inventory management, and tank inspection. The tool works with metric and imperial dimensions. Use it to determine remaining capacity from a depth measurement or gauge reading.

Input guidance

Enter tank diameter, length, and current liquid depth.

How to use this tool

Enter tank diameter, length, and current liquid depth.
Run to compute filled volume and percent full.
Use results for tank level monitoring and reorder trigger planning.

Horizontal Cylindrical Tank Contents

Calculate liquid volume in a horizontal cylindrical tank from depth.

Results

Tank Diameter: 2.00 m

Tank Length: 3.00 m

Liquid Depth: 0.800 m

Segment Area: 1.1735 m²

Liquid Volume:

Cubic Meters: 3.5204

Liters: 3520.44

Formula or method

Liquid depth is clamped between zero and the tank diameter.
For partial fills, the handler uses the circular-segment area r^2*acos((r-h)/r) - (r-h)*sqrt(2*r*h - h^2).
Filled volume is the circular-segment area multiplied by tank length; empty and full tanks use zero area or full circular area directly.

How to interpret the result

Review units, boundary conditions, safety factors, material assumptions, and applicable standards before using this as design input.

Confidence and limitations

Outputs are deterministic formula results and depend entirely on input quality and units.
Results are for planning and learning; verify with domain standards before safety-critical use.
Rounding and finite precision can introduce small differences in edge cases.
