Heat Transfer: Model Show Slower Flux Retains Larger Percent Hot Volume. Why?
(OP)
Imagine magma flowing into two chambers in the Earth from some deep source. It's hot (1500 K).
For one source (SOURCE 1), the flow of magma into the chamber is 10 m/s
For the other (SOURCE 2), it flows in at 5 m/s
After 5000 years, we measure how much of the magma is still above 1150 K
Although the total volume of magma over 1150 K is larger in SOURCE 1, the PERCENT VOLUME that is hotter is larger in SOURCE 2
I've attached a simple diagram so you can visualize it
(VOLUME 1.2/VOLUME 1.1) < (VOLUME 2.2/VOLUME2.1)
Why would that be?

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!

Your graph units and scaling make no sense; what are m/a? Why does your vertical scale go to 1000% Also what are the relative diameters of the stacks?

And your right - once I really thought about surface area the results look even more wrong because of the area/volume problem ... I am going to have to re-calculate the set myself and see what the problem is because I can't think of a good reason for this.
And the y-axis went to 1000 because I was in a hurry and made a mistake. You can read it as "100"
