This isn't the account I was talking about. The flood account should be read completely instead of making assumptions. The bible doesn't say all the water came from rain fall. I was hoping you'd just read it and discover it for yourself since that is always more meaningful to the learner.
So I've recalculated the volume of water. The bible says the flood covered the mountains plus some number of cubits. Since you refuse to link which biblical flood example you are referring to I took a look online. Most young Earth creationists say that the Earth was different before the flood so I will take the conservative path and estimate the pre-flood mountains at a whopping 200ft.
Doing the calculations like Subyman suggested gives us an answer around 1-2x10^9 km^3 of water.
This works out be
only 320 in/hr of rain.
Across the roof of the ark it would be:
150,000GPM. That's equivalent to to the output of 8 space shuttle main engines for comparison.
Now the bible saying some of the water came from below means that some of the 320 in/hr came through the ground or elsewhere.
The highest recorded hourly rain rate was 13 in/hr. The highest recorded rain rate per minute was about 1in/min or 60 in/hr.
So let's assume our biblical rainstorm is twice as bad as the worst rain rate recorded: 120in/hr. That leaves about 200 in/hr to come from the ground. That amount of flow everywhere would have dislodged the ground
everywhere. Or created huge geysers everywhere.
The biblical story of a world wide flood is scientifically impossible. You know it. I know it. Everyone knows it. So why are the creation "scientists" trying to support this story with made up science. You either know it's an allegory of you have faith God made it happen. If you have faith there's no reason to try and use science to fake support.
