You'll get a pressure drop after the impingement but along comes the velocity with it. You want slightly less pressure after the impingement for the impingement to actually do it's work. That'll send the water through the channels and thinning the boundary layer as it hits the base and shoots across through the channels. That's how Cathar's works but his is designed also to aid in flow to all the channels - Hence the rectangle nozzle. I'm still undecided about the pin concept since I havn't tried it yet. I know it helps eliminate the stagnation point where warm water can get stuck inside the jet but I think it would allow heat to travel up in the pin and heating the water before it hits the base. Not sure, probably a give and take situation.:shrug:
