i wonder how many lbs. per square inch my 55 gallon fish tank is applying to my floor?

Question

the tank filled water weighs around 500 lbs., it's 48 inches long and 13 inches wide, water weighs around 8.3 lbs per gallon, any math wiz

Answer 1

easy math

I bet it has a 1/2 inch rim around it so only psi on that part.

55 gals x 8 lbs per so about 400 pounds.

about 120 inches around so round to 100, 4 psi

Answer 2

I was counting in my head while reading through your list of fish. Using an average length of a half-way grown fish estimate and allowing for the rule of 1 inch of fish per 1 gallon of water, with what you have now, you're already up to about 48 inches of fish and they aren't even all the way grown yet. I know how much we all want more and more fish because they're so beautiful and fun to watch, but, for the health of the fish, we need to learn some restraint and know when to say enough. The elephant nose would be okay with fish equal its size and larger, but the smaller fish will be dinner in no time, plus, they can grow to 9 inches, so probably not a good choice. You could get away with a dwarf puffer as they only grow to 1 inch in size, but keep an eye on the growth of the rest of the fish and using the 1 inch per 1 gallon rule, do your math and when they start hitting about 50, it's time to think about a larger tank, because these fish will eventually exceed the allowable amount of this tank. You need a good selection of foods for this group of fish. Cichlids have special foods and feeding requirements, catfish have their own special foods and feeding requirements and then they all need their special treats of brine shrimp, krill, blood worms, etc., spirulina, fresh fruits and leafy veggies.

Answer 3

If the weight is uniformly distributed over the area of the base of the tank, the pressure is simply total weight divided by the area:

500lb/(48*13) lbs/sq inch.

Answer 4

456.5 lbs per sq in. plus the weight of the tank itself.

Answer 5

Then it would be 500 lbs/sq IN
