Obviosly, mixing between the two tanks takes place under the circumstances I outlined, probably primarily in the manifold. If mixing did not take place, what would be the point of having a communicating manifold?
The issue I was addressing initially had to do with the possibility of each separate tank having a different level of O2 when using nitrox. I understand that gas from one tank will not flow into the other unless there is a difference in pressure, and that there cannot be a pressure difference if the tanks are communicating.
On the other hand, if there is a pressure difference because the valve between them is closed there will indeed be a mixing of gases when the valve is opened. This is the situation that was described by a poster who had consequently called a dive under those circumstances, and to whose post I responded. Then you decided to stick your nose in for no valid reason, apparently motivated by that inflated ego.
Obviously, if the pressures in both tanks are equal, there will be little or no mixing in either tank, but there surely will be in the manifold. You know I'm correct but you find it galling to do anything but make unjustified remarks about my competence.
I'll leave this 'debate' now because you have chosen to complain to the moderators. I received both your complaint and their reply. You were basically slapped down and told to fight your own battles, and that they would not interfere.
I leave you victorious on your pathetic field.. This is not a debate. It is an exposition of your infantile anger an inability to be objective. Running to complain to mommy and daddy is typical of your sort. In 12 years on this board I have never complained about anything or anybody.
The moderators did not chastise me in any way. Quite the contrary. You were told what to do with your complaints in no uncertain terms.
I'll leave it at that. The floor is yours, Mr. Quizzling.
