Lifting Weight Calculation.

A
list of common aquarium sizes can be found in chart form here
In metric, this calculation is
quite easy because 1 cubic centimetre of water has a mass of 1 gram, or 1 litre
of water has a mass of 1 kg. Thus, the water in a 200L tank will have a
mass of 200 kg (don't forget to add the weight of rocks into your
estimate!). If you need to work from tank dimensions, multiply the length
times width, times height in centimetres to obtain the mass in grams.
For those of us having to
work in inches and pounds,
| 1 gallon
of water at 4°C
| =
| 8.57 lbs
approximate weight
|
| One foot
of fresh water depth
| =
| .445 psi.
|
| 231 cu
inches (in ^ 3)
| =
| 1 gallon
|
| 1 cu
foot (ft ^ 3)
| =
| 7.48
gallons = 1728 in^3
|
Example:
44x16x16 tank = 11264 in^3 =
48.76 gallons.
Tank will weigh 418 lbs
(roughly) (+ rocks which have an SG much higher than 1, so you can
*roughly* say " + rocks ")
The pressure at the bottom of
the tank will be 0.59 psi, or 85 psf, roughly 13% more than the standard
loading for code construction, so catch an extra joist or three with the
stand!!
Along the bottom strip of the
tank, you will have a total (uniformly spread side to side) force of (
15.5/12*.445*44 = 25 lbs) pushing outwards against your joints.
The total force on the long
side will be ( 8/12*.445*44*16 = 208 pounds).
Note: In general, this is NOT
half of the water weight. This is a coincidence due to the same bottom and
side shape.
