Poor accuracy in table listing

Tank wider than tall

sf = h/v (greater than one).

Then create a table of TankCalc results and multiply all the volume results by this ratio.

Worked example:*TankCalc versions 7.3 and higher have a scaling factor entry to accommodate this tank type. Use the above instructions, but enter the computed ratio into TankCalc itself.*
Yes, sort of. Take the vertical dimension of the tank and perform all the usual computations. Then create a scaling factor (sf) created by dividing the horizontal by the vertical dimension:

sf = h/v (greater than one).

Then create a table of TankCalc results and multiply all the volume results by this ratio.

Worked example:

"The horizontal cylinder vessel Length is 2560mm. The vertical diameter is 1470mm, the Horizontal diameter is 2255mm, the Hemisphere caps left and right are, radius "r" is 175mm."

TankCalc entries for this tank (all millimeters):Full volume result: 4740.75 liters

- L = 2560
- R = 735 (diameter divided by 2)
- r = 175 (both left and right)

Scaling Factor sf = 2255 / 1470 = 1.534

Adjusted full volume result: 7272.31 liters (4740.75 * 1.534)

Table procedure: Create a table of results in TankCalc, transfer the table to a spreadsheet, and multiply the volume results by the computed correction factor.

80% Filling Rule

[ *This exchange, which continues a conversation on other topics, refers to the liquid-phase storage safety rule that requires no more than 80% fill by volume.* ]
