A 0-100 foot tank with a specific gravity of 0.8 has the highest measurable level. What is that level?

Explanation:
When level measurements are tied to hydrostatic pressure or buoyancy, the liquid’s density (specific gravity) affects how the signal maps to a physical height. Most level devices are calibrated for water (specific gravity 1). If the liquid has a lower density, like 0.8, the same sensing signal corresponds to a shorter vertical distance on the scale. So, in a 0–100 ft tank, a liquid with SG 0.8 will reach the maximum indicated level at about 0.8 of the full scale. That gives a highest measurable level of 100 ft × 0.8 = 80 ft.
