Which capacity range is associated with the floating roof tank?

Which capacity range is associated with the floating roof tank?

• A. 50,000 to over 1,000,000 gallons
• B. 8,500,000 gallons
• C. Varies due to construction
• D. 1,000 to 5,000 gallons

Answer: (A)

Floating roof tanks are built for storing large volumes of liquids, especially hydrocarbons, and the floating roof helps minimize vapor losses by reducing the vapor space as the liquid level changes. Because these tanks come in a wide range of sizes, their capacities typically start around tens of thousands of gallons and can exceed a million gallons. The range of 50,000 to over 1,000,000 gallons best reflects that broad, common spectrum, covering both mid-size and very large tanks. The other options don’t fit as well: 1,000 to 5,000 gallons is too small for a floating roof design, 8,500,000 gallons is a single very large figure not representative of typical ranges, and “varies due to construction” doesn’t provide a usable capacity range.
