Silly me.
Had intentions of look-see at Impingement on my 6mm bped block
Have only just realised that I am probably on the upper bp thickness limit to get any improvement from impingement cooling.
Playing with data from http://www.electronics-cooling.com/h...01_may_a2.html (Ta Bill) and http://widget.ecn.purdue.edu/~eclweb/jet_benchmark/ (Ta g-f) suggests:
Speculative Performance
Intention 3mm noozle .Impingement Cooling Diameter 15mm (max) with h ~ 100,000W/m*m*c for 200LPH flow.


Think I need a thinner bit of Copper.
