Ah, you just had to bring math into the subject, eh? Well, we might as well get into the nitty gritty of it to show that you are wrong.
Even if the water pump pumped 50 GPM (which would be pushing it for even a high volume pump) and the bottom radiator hose was 1 1/2" diameter, it would take a .55 psi pressure differential to flow the 50 GPM through the system.
In other words, as long as our radiator cap holds .55 psi, no collapsing will happen.
If you have a cap that holds no pressure (bad rubber on the cap), and a clogged radiator, then yes, your bottom radiator hose can collapse.
But, I digress - you can believe what you want, and I will believe the facts and physics.
Good day.
