What is the term for a tank with a roof that floats on the liquid surface?

• A. Floating Roof Tank
• B. Cone Roof Tank
• C. Fixed Roof Tank
• D. Underground Tank

Answer: (A)

Floating roof tanks have a roof that rides on the surface of the stored liquid, which prevents a large vapor space above the liquid and reduces evaporation losses. This type of tank is called a floating roof tank. The roof can be external or internal, each designed to move with the liquid level and seal around the edges to minimize vapor escape. This approach contrasts with fixed roof or cone roof tanks, where the roof is rigid and does not float, and with underground tanks that aren’t above-ground structures.
