Most of the earth’s land mass is at fairly close to the current sea level, mountains and large plateaus form only a small part of land area, so to an first order approximation, we can ignore the volume taken up by mountains when we calculate the volume of water required to raise the sea level 29,000 feet to flood the top of the highest mountain. It turns out that requires an addition of 4.5 billion cubic kilometers of water, as can be determined by subtracting the volume of a sphere 9 km larger than the current radius of the earth (the size of an earth flooded to drown the tallest mountain) from the current volume of the earth.
So it seems it would require the addition of just under 3.46 times as much water as currently in all of the world’s oceans to drown the tallest mountains. Round that down slightly to account volumes of existing mountains and plateaus, say around 3.4 times.
Adding 3.4 times as much water in the ocean to the atmosphere, so it can rain out in Noah’s eponymous flood, would increase the atmosphere pressure of the earth from 14.7 psi to about 19000 psi. At 19000 psi pressure the air would be twice as dense as water. Breathing it would be like breathing molasses.
To keep all the water in the air that’s about to rain out in the vapor phase so as to not be prematurely raining out and ruining Noah’s eponymous ark while it is still under construction, the atmosphere temperature would have to be high enough to keep so much water vapor from exceeding the saturation pressure.
Unfortunately I failed to locate any engineering saturation pressure plot that goes up to 19000 psi. The highest doesn’t even go 1/10 that high. But at 1/10 that pressure, the saturation temperature is already 350 degrees Celsius.
To put it differently, even if the atmosphere Noah breathed contained just 1/10 as much water as required to precipitate out and drown the tallest mountain, that atmosphere must have already been hot enough to melt lead to keep all that water from supersaturating the atmosphere and instantly raining out.
Noah must have been quite the champ to be able to work so hard at building the ark while breathing air as thick as molasses and hot enough to at least melt lead.
I think that you are assuming that all that water would exist in a vapor phase in the atmosphere.
The tanakh says that fountains of the deep are also opened up and water popped up from those fountains.
Genesis 7:10 KING JAMES VERSION
And it came to pass after seven days, that the waters of the flood were upon the earth. {7:11} In the six hundredth year of Noah’s life, in the second month, the seventeenth day of the month, the same day were all the fountains of the great deep broken up, and the windows of heaven were opened. {7:12} And the rain was upon the earth forty days and forty nights. {7:13} In the selfsame day entered Noah, and Shem, and Ham, and Japheth, the sons of Noah, and Noah’s wife, and the three wives of his sons with them, into the ark;
^^^^^In the text above, we can see 7 days.
7 th day of the month.
40 days and 40 nights.
3 sons and 3 wives.
So, the author tries to hit the magical numbers a few times (3, 7, 12, 40).
It also says that the fountains of the great deep broken up.
I don't know how deep they mean but if it is suppose to be 1 km and more, it would be at boiling point.
I haven't done the math but this could potentially mean that all lifeforms would be steamed to death.
To hold enough water to drown mountains 9km high, the reservoir of water would need to be at least 9kms deep, that’s assuming the reservoir is a void filled with water, not just an aquifer in which the water only constitute part of the volume.
Also, for 9km’s worth of water to boil out of the earth, the surface of the earth would have to subside by 9kms. Which creates the interesting problem of as the surface of the earth starts to subsides, the radius of the earth reduces and the surface area of the earth shrinks. So the entire crust of the earth would instantly be placed under intense compressive stress, and would have to shorten to accommodate the compression, which would also close down any cracks or apertures through which the water can come out.
So, I Don’t think the “water coming out of the ground” hypothesis reduces the magnitude of the risibility of the genesis by even the most tiny amount here.
