And how big do you think the error will be?? Probably no more than 0.1C. But they used two thermocouples, one on inlet and one on outlet, and recorded both with a data system.
"Please post a link to the report describing the equipment used to accurately measure the volume of outgoing water and its temperature. Note that I said, “accurately”—no bathroom scales, please.
Info is not in the written report....it's in one of the videos. But it's the same totalizing flowmeter shown in the 6 Oct. demo on the output of the heat exchanger. They actually had it on the "input" water rather than the output. They focussed a video cam on it to get flow rates at intermediate times.
BTW, I don’t have a problem with bathroom scales or any other sort of improvised equipment.
Why isn’t this flowmeter listed in the report’s canonical list of measuring devices used for the experiment?
