Oh well, you're probably right Bill
Perhaps there is a more appropriate term. I am trying to quantify the effectiveness of a given design, at a given baseplate thickness, across various flowrates. "h" or at least an effective average something like a global "h" seems to me to be a reasonable approach. I'm not trying to calculate it, rather compare what other parameters should be doing when it changes. Fit this to existing data and thereby generate some kind of figure of merit for a given design.

I understand I think. Agree.
