Volumes and Capacities of 

 Circular Tanks 



For water depths less or greater than 1 foot, multiply the tabulated volumes and capacities 

 by the actual depth in feet. 



For tanks larger than 20 feet in diameter, multiply the volume and capacity of a tank 

 one-half its diameter by four. A 30-foot diameter tank, for example, has a volume of four 

 times the volume of a 15-foot tank. 



For intermediate tank sizes, volume = 3.14 x ( -j diameter) x water depth; capacity = 

 volume X 7.48.
