I don't care how much water is being perfused, why can't I just use standard resistors which give a perfusion rate of 0.6ml/minute for all applications?

Use of this flow rate for smaller diameter manometric channels (less than 0.6mm) generates a very high back pressure because of the resistance of the manometric channel to such a relatively high flow rate. This makes it impossible to make technically adequate pressure measurements with both the sleeve and sideholes. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
