Water Weight

Originally posted by Dolphin 2 Water weighs about 63 Lbs. per cubic foot. Or 1 gram per cubic centimeter (1000 kg per cubic meter). You might also like this article called Archimedes' Bathtub.

In other familiar terms... 8.34 pounds per gallon of water 7.48 gallons per cubic foot of water for every 2.31 feet of water depth there is 1 PSI of pressure or .433 PSI per foot of water depth

Migawd...any moment now & you'll be off onto methods to exactly measure pools for the purpose of official records...

I am a certified water treatment and water distribution operator. I have all of this water stuff in my head that I seldom use so maybe I will start measuring pools!

Here are some facts about the physics of fluids (known as “hydrostatics” in this case) and their practical application to swimming. Objects actually weigh the same in water as on land. However, when submerged in water, there is an upward force (called buoyancy), which opposes its weight. If the force of buoyancy equals its weight, the object will float. Water weighs about 63 Lbs. per cubic foot. If an object of a given volume displaces a volume of water that weighs the same as what the object weighs, it will be 100% buoyant. This bit of physics might be a comforting fact to those who are just learning to swim and are afraid of sinking: The volume-to-weight ratio for most people is such that a person will become 100% buoyant when they are submerged at chin level -and they will not sink any further. Happy Swimming! Dolphin 2 :D

thank you very much :D
