A 450 foot ark must weigh 24,300 tons to sink 15 cubits into the water until grounding when 15 cubits of water were over Ararat.
I have always known this since realizing the 15 cubits was the depth of water (i called it ballast) but i guess here a few weeks ago i learned the word draft or drought.
QUOTE:
http://www.biblestudy.org/basicart/sizeark.htmlThe displacement tonnage of the ark, which is the weight of water it would displace at a draught of 15 cubits, would be more than 22,000 tons. By comparison the U.S.S. Salem, a 716-foot-long heavy cruiser commissioned in 1949, has a displacement tonnage of 21,500 tons.
With this inspiration, I can google the weight of water to do the math. This is calculated by the fact that the water which is displaced must have the same weight. Thus 450 feet by 75 feet and 22.5 feet deep of its 45 foot height. That much sea water at sea level weighs 24,600 tons and so the ark had to be that weight (remember now the land dropped, the water didnt rise).
water weight
Weight: 62.416 pounds per cubic foot at 32°F
Weight: 61.998 pounds per cubic foot at 100°F
15x 50x 300 = 225,000 cubic cubits displacement
45x 75x 450 = 1,518,750 cubic foot ark
draft (draught) of 22.5 feet for 150 days until grounding
22.5x 75x 450 = 759,375 cubic feet displacement
A cubic foot of seawater weighs between 63.6 and 64.3 pounds at 40 degrees F.
at surface just over 64.1 lbs per cubic foot
64.1 pounds x759,375 cu.ft. = 48,675,937 lbs = 24,338 tons
(quote from link about ark says more than 22,000 tons)
This means the weight of the empty ark
plus the weight of everything on it was 24,338 tons
in a space of 1,518,750 cubic feet.
I thought I posted it here, but since I am not sure whether anyone thinks I over-post or not, I may have posted it only in Google Groups. I have been saying 15-foot ballast (draft) for 20 years, yet these same thinkers who pick up on that cannot pick up on the fact it was 7 animals not 7 pairs. They insist that it is for breeding, failing to see that the 3 pair are for breeding as a product of things like fur and wool and milk, and the 7th is to sacrifice for skin and the probability for meat as did prove true. When it says God Jehovah gave them (man) skins to wear, it doesnt say they only took the skin off dead animals, no record says that animals were never killed by man before the Flood. So we do not know at what point in time man felt free to kill animals for product use, as he does vegetation for eating. Clearly, it was done or a 7th would not have been brought to sacrifice. (Granted with Noah, it could have been an "if" we need it, concept.)
