1) No it isn't. You have a condensate return path with a pump that could easily create a slight vacuum on the outlet side.
2) No it isn't. I can easily see Rossi just setting them to max settings and letting them run.
3) The flow rate varies. Look at the tapestry of data. And they are clearly rounding. And in some cases, they are probably mindlessly copying the same value from one day to the next.
4) The return pipe doesn't need to be full. Jed makes this same mistake. How do you know whether it is purely a gravity return? That's not what the record indicates.
5) Murray had a setup of his own that didn't match the Doral setup. He even admitted this in his depo. The flow meter spec states the error bars in partially filled pipes. Rossi's attorney hit Murray over the head with it.
OK, this is all feeling very familiar. It has been fun rehashing, and we both know where we stand. So for new readers I'll give it one more shot and then I've got to move on for now to do real work.
1) It cannot easily create a slight vacuum on the outlet side and simultaneously be a "working fluid circuit". You don't know what your talking about. If you took sophomore level engineering thermodynamics, you would understand why.
2) Using precision dosimetric pumps all set to 100% makes no sense.
3) The flow rate is unrealistic in that it varies very little. Thanks for admitting that "mindlessly copying" is a reasonable and likely alternate explanation.
4) We know that it was a gravity return because of the open to the air tank return tank (see photos).
5) If the return pipe is not full, it WILL measure incorrectly - the manufacturer states this explicitly in their specs.
And we haven't re-litigated the imaginary heat exchanger, the pipe strips, the fake engineer, insulation on significant portions of the serpentine pipe in the JM-side container (??), the Grundfos pump, etc.
But alas, I'm out of time, so new readers will have to jump back to those discussions if interested.
