THis looks surprisingly like a "pH get off your ass, quit playing Doom3, and generate tons of head loss vs. flow curves" moment to me.

This is going to get messy quickly. I am thinking that I will be forced to test some radiators before too long too... shit

//edits: this will be another good reason to test some complete kits; we can have some real configurations with final flow rates known and see how close the model gets us
