The equipment parameters are shown in the diagram below: Metallization tank – dimensions: diameter 1000X2830, volume = 1.5 m3. Metallization storage tank – dimensions: diameter 1600X3550, volume = 1.5 m3. Recovery tank – dimensions: diameter 1000X1500, volume = 1.2 m3. Do these dimensions refer to from one end cap to the other? If so, the volumes would be higher than indicated. It still refers to the total height
External dimensions: Diameter 1000X2830; Volume = 1.5 m3. It is an interstitial storage tank. External dimensions: Diameter 1600X3550; Volume = 1.5 m3. How is the volume calculated?
It’s not calculated; the parameters for the customer’s device are listed as such

The external dimensions generally refer to the maximum outline dimensions, which are used for packaging, transportation, and determining the required installation space. The actual volume should not be calculated based on these nominal dimensions; especially in the case of pressure vessels, which have many arcs and rounded corners, and may also have spaces occupied by pipelines and other components inside. As a result, the actual volume is much smaller. This varies depending on the complexity of the equipment and the regularity of its shape, with the volume being specified by the manufacturer.
Since they gave me these dimensions and asked me to draw the equipment diagram, should I calculate based on volume or…
Put simply, the external dimensions of a device refer to its outline size, which is a measure of the amount of space the device occupies externally – that is, the space it takes up, as mentioned on the 6th floor. This is a term used to describe the maximum size of a device, and it is utilized in operations such as the packaging, transportation, storage, and installation of the device. Volume refers to the space occupied by the equipment, and this parameter should be determined by the role of that equipment in the manufacturing process. Of course, the final value is usually rounded. For example, the 15 m3 value mentioned by the poster might actually be 14.98 m3 in terms of the actual calculation. The specific reasons are explained in detail on page 4. If you draw a diagram of the equipment (for reference), it is essential to meet the customer’s requirements: the volume must be no less than the specified value, and the dimensional dimensions must also not exceed the required levels. :)
