If it rained for 40 days and 40 nights that's 960 hours of continuos raining.
If Mt. Ararat is 16,854 feet tall that means that the water depth was actually 16,874 feet, because the water was 20 feet over the top of the tallest mountain.
So given a height of 16,874 feet and 960 hours it means that it would have had to rain 17.57708333 FEET PER HOUR. That's 210.925 INCHES OF RAINFALL PER HOUR.
I was once on a planet where it rained 767 inches per hour for 1,872 hours. I thought it was a heavy rain but the locals said that they get a lot worse every century or so.
