Sep 15, 2019September 15, 2019. Spherical Storage Tank Design:- The most common shape of a storage vessel is a cylinder with two heads which are either, hemispherical, elliptical or tori-spherical. Spherical vessels have larger surface area per unit volume. The advantage of a sphere over a horizontal cylinder with the same volume is increased by the static eritrea the spherical tank fire volumeSelecting and Sizing Water-Storage TanksWith elevated tanks, the cost per unit volume decreases significantly as the tank capacity is increased. A 100,000-gal (380,000-L) elevated tank has approximately twice the cost per unit volume of a 500,000-gal (1.9-ML) elevated tank (Figure 5-4). For reservoirs and standpipes, an increase in capacity also lowers the cost per unit
