2)h is the same as alpha - coificient for heat transfer in W/m2K right?

1) Have had only limited success with the nozzle calculator.It only seems to be relevant with nozzle diameters below ~3mm for impingement regions near the die region(~15mm diam?).
Looking more towards "the Billa link" http://www.electronics-cooling.com/h...01_may_a2.html for the answers .
2) That is my understanding.
