Horizontal Elliptical Tank - On-Edge

Calculate the volume, capacity and surface area of a horizontal on-edge elliptical tank/container.

The tank here looks like a squashed circle, and for this type of tank/container, the height has to be larger than the width. This calculator uses inches for measurements.
