How Heavy is too Heavy?

I had to laugh about your ideas concerning the weight of "said fish
tank"
and what structural
modifications will be needed. I have just one small question that you
should
consider,before
rewriting the Laws of Architectural design. How heavies the bath Tub,
plus
your weight.
Also ,,Do you own a Water bed..

it's obvious that you've never been involved with building a house before,
because if you had, you would know they already have guidelines for
bathrooms, and laundry rooms, that detail where and how a tub/shower/Jacuzzi
can/should be laid out... They are almost always in either high integrity
areas, corners, load bearing walls, etc... for the specific reason, they'll
be heavier.... If you are building a house, and tell the architect that you
are wanting a 250g tank, he'll ask where do you want it... You say, in the
middle of that room... He'll laugh, and reinforce the floor... If you said
2nd floor, in the middle of the room.... he'll put alot of enforcement below
that floor and the floor below....

No kidding! A full 250 would weigh over 2200 lbs.

Marcus

Are you talking American gallons or Imperial gallons.

Even though I'm in the UK it is standard practice to refer to aquarium tank
size in US liquid gallons. At least in this newsgroup.

Marcus

So that would mean that a 125 gallon tank , would in fact only be a 32
gallon tank.
working on the assumption that one American gallon is really only 1.2
litres or one quart Imperial, This gets more confusing the further we get
into it,,,
So how heavy is the fat lady that sits on the water bed, and what's the
water content.

An American gallon is 1.2 UK (imperial) gallons, and 3.79 litres or 3.33 UK
(imperial) quart, not 1.2 litres or one imperial quart. So 125 US gallons is
104 UK gallons, not 32!

Of course, you meant to say that one Imperial gallon is 1.2 American gallon.
One American gallon is thus 0.832 Imperial gallon.

direct from a conversion chart for international travelers:
1 American gallon = 0.832 Imperial gallon
1 American gallon = 3.785 litres
1 Imperial gallon = 4.546 litres
1 kilogram = 2.204 lbs.

from memory of physics class (is this correct?):
1 litre of water = 1 kilogram

therefo
1 gallon of water = 8.34214 lbs. = 3.785 kilograms

So, to find the weight of your tank, multiply this figure (lbs. or
kg, whichever you are more used to) by the volume of your tank then add
in the weight of the tank itself, the stand, all the equipment, and the
decorations. And if you will have large fish in it, add something for
them, too. (Small fish are probably negligible weight in regards to the
infinitesimal water volume they'll displace, but large fish do weigh
more than the measurable water volume they will displace.) This is how
much it will weigh fully set up.

To find the force exerted on your floor, measure the area of the
stand which will actually be in contact with the floor. Divide the
weight by this area and you will have the force. (I forget the units of
force. I believe it's Newtons in metric, but don't remember it's g/cm2
equivalent. I don't believe I ever learned the English system unit name
because science classes are the only place we crazy Americans use the
metric system.)

Anyway, if it is a solid piece of wood or whatever which is
contacting the floor, the area will simply be the length X the width and
will be a fairly large figure. But if your stand is like the metal one
my parents bought back in the 70's, and has little legs which are
actually the only part in contact with the floor, this will be a very
small figure. My parents' old stand probably only had a grand total of 4
sq. in. touching the floor, so even though it was only a 10 gallon tank,
the force exerted on the floor was huge! (I'm not going to take the time
to calculate this figure now, but I remember the apparently permanent
dents in the brand new plush carpets in the brand new house we lived in
for a couple of years.)

weight by this area and you will have the force. (I forget the units of

Newtons are the units of force, dependant on gravity. Force = mass x
acceleration, so that's kilograms x gravitational potential, which is 9.807
m/s

Since gravity is fairly constant, we can use kilograms or newtons to
describe the force exerted on an object by it's weight.

An interesting fact, since gravity or gravitational potential is determined
by the distance to the centre of mass, and the Earth not being a perfect
sphere, gravity at the equator (sea level) differs by 0.5% from that at the
poles. But for the purposes of calculation, 9.807 is the figure given in our
data books.

Actually I have built houses and renovated a few as well, Not that I am a
builder,
But weight distribution is the same the world over.. Tell me as you know so
much on the subject, perhaps you can list the number of suspended floors
that have failed, due to an over excess in weight.. You know the thing,
Bath tubs fitted with large overweight ladies,
or what about Piano's. I have a friend that collects up-right piano's , He
has about five of the things, in his lounge Room,,[please don't ask why'
we have done that ] House up on brick piers, with the normal timber joist
arrangement..
Another friend is also into fish, He has some 50 odd tanks in his tank room,
Timber house,
raised on Piers, nothing special.
My own little set-up, consists of a 3 bedroom place, up on brick piers
this is getting repetitive ] again all standard, two double water beds, a
double spy bath, Four foot fish tank in the Lounge room, in an Upright
Piano stand.. The sun room is 35 square metres
has a full size antique Snooker table , and a couple of six foot tanks..
and to date
nothing creaks or drops through the floor.. So really I think your talking a
load of Crap..

Love bassett..
