Calculate the Capacity of an Agitator Conditioner

07/04/2016  59.85 time 100 equals 5,985 cu. ft. (total volume 24 hour agitation). Therefore, 5,985 times 2 equals 11,970 cu. ft. (Total volume 48 hours agitation). We find that 15′ x 4.5″ x 16′ and 1″ Bolted Steel Tank has an available capacity of 2,860 cu. ft.; therefore, four of these will handle the job.

Agitator (device) - Wikipedia

An agitator is a device or mechanism to put something into motion by shaking or stirring. There are several types of agitation machines, including washing machine agitators and magnetic agitators. Agitators can come in many sizes and varieties, depending on the application. In general, agitators usually consist of an impeller and a shaft. An impeller is a rotor located within a tube or conduit
