Drum Volume

Description

Drum Volumes is simple--providing you with volumes for vertical and horizontal drums, box vessels, and spherical vessels at your specific liquid level, and also at 10%, 25%, 33%, 50%, 67%, 75%, 90%, and of course 100% liquid level.

RESIDENCE TIME: You can also calculate residence time between two liquid levels and a net liquid flow (in or out of the vessel) and the app calculates the residence time between the liquid levels you set.

Volumes reported are in ft3 and gallons (ft3 total, strapping data in gallons only).

For vertical drums, the liquid levels on the strapping chart (10%, 25%, 33%, etc...) neglect the bottom head, so you'll see only the tan-tan liquid inventory, but the overall liquid volume inventories do include the heads.

For horizontal vessels, I'm sure you're asking "What about the heads". Yes, the partially filled horizontal cylinder and partially filled horizontal heads are included. The cylinder equations I used were derived using simple geometry, which just took a long time to figure out. The heads use correlations based on Perry's Chemical Engineering Handbook charts, statistically derived. The R-squared value for the equation use versus the chart values is greater than 0.99999, so the error for the partially filled head volumes is much less than 1%, and therefore, overall, the entire inventory is in error usually by MUCH LESS than 1%.

Heads assumed for both vertical and horizontal designs are semi-ellipsoidal heads. The volume equation used for the heads is: PI * D^3 / 24. If you desire different head designs, send me feedback and let me know.

Do you have other shapes to run on this app, or desire other key features, let me know please at my contact information on the app URL.

What's New in Version 4.1

Fixed the bug in the volume converter which shows that 1gpm = 60 gps, which we all know is wrong...the labels were in the wrong place, otherwise, the other calculations worked fine...
