That's the problem. If you count on only one person to fill the data, the DB won't be nearly useful before 1 or 2 years, and i'm optimistic.
One needs the curves (actually, the data behind them) for every pump, piece of tubing, rad, fan, and waterblock around. The software can interpolate between curve points, using linear or more elaborate techniques, but too many missing points and you'll get inconsistent results.
That said, many curves show a nice inverse exponential look, which can be neatly approximated. But one needs to consider each case (pump, rad, etc) and each subcase to match the math functions as exactly as possible. Not a short work either.
Also, some parameters are very hard to code, like turbulence behaviour for example. This is the domain of finite elements calculus, and out of reach for a small java applet...
We need to define exactly what to expect from that piece of software.

I'll start a new thread to discuss a possible simulator tomorrow.

If you don't mind gmat, I'll paste your post into that thread.
