Is a liquid ammonia storage tank claimed to have a capacity of 20 cubic meters actually capable of holding 20 cubic meters? Will the actual internal space be a bit larger, a bit smaller, or just right?
Logically, there should be a loading factor; you need to consider whether it’s the effective volume of 20 or the total volume of 20.
Additionally, the total volume is usually rounded off, so if the total volume is 20, the actual volume might be a little over 19, or just a bit over 20
20 is the standard value; other factors are taken into account during design, and the actual volume will exceed 20 cubic meters. The liquid level will be kept at 20 cubic meters, with any excess representing a safety margin. In my personal opinion,
The nominal volume is 20 cubic units; generally, the total volume is greater than 20 cubic units. The total volume isn’t a whole number, so it is recorded as exactly what it is. In some cases, the nominal volume refers to the filling volume; in such situations, it is necessary to divide by the filling factor to obtain the calculated total volume, and the actual total volume should be greater than this calculated value.
To avoid the high forces caused by the thermal expansion and contraction of liquids, as well as overpressure or other hazards resulting from other factors, flexible tanks are equipped with a filling factor; thanks to this factor, the nominal volume is naturally smaller than the actual empty volume.
A certain margin is reserved as per the design, and the actual value will be slightly greater than 20
