Safe height-to-diameter ratio (h/d) for liquid/petroleum fuel storage tanks exceeding 45 kiloliters capacity is under _________________?
Show answer Hide answer
Answer: A. 1
Explanation
For stability and safety, the height-to-diameter ratio for large liquid storage tanks exceeding 45 kiloliters is kept under 1. Keeping the height less than the diameter ensures a low center of gravity resistant to seismic and wind loads. Large-capacity storage vessels require broad foundations and low aspect ratios to prevent structural tipping hazards. Petroleum storage tanks hold massive quantities of flammable liquids requiring rigorous structural safety standards. Wind overturning moments and foundation soil bearing pressures increase significantly with taller tank geometries. Storage tank design codes establish strict dimensional limits based on total fluid capacity and local environmental hazards.
A height-to-diameter ratio of 2 is too tall for large petroleum storage tanks and compromises structural stability. A ratio of 3 creates an unstable vertical column vulnerable to wind overturning and foundation failure. A ratio of 3.5 represents tall vertical distillation columns rather than large-capacity liquid storage tanks.
