OK, interesting concept. I was thinking along the lines of how a heat pump operates. It consists of a closed system with a pump(compressor) and a strong restriction to the flowing fluid as well as heat exchangers. A low pressure return pipe carries the active fluid in vapor form to the pump. If sufficient heat is not absorbed by the expanding mixture then some of it remains in the liquid form. I wonder if a significant portion of that mixture in Rossi's case might be vapor, leading to false reading within the gauge ahead of the pump?
This is merely a conceptual idea to digest.

The surface area is very large. In less then 3D (scale of the tubes in 1D in comparison to other), turbulence can go from small vortices to high, and when it exits to large tubes it goes from high vortices to low. Depending on the design, a lot of cavitation may form and accumulate in the flow meter, if no system to elimate bubles is developed. 2016-08-08 21:32 GMT-03:00 David Roberson <[email protected]>: I agree, the pump might actually lower the pressure at its input enough to allow the water to vaporize if the flow is restricted ahead of the gauge.
