Alright, if it's conclusive without the thermocouples....
Does anyone have a decent water capacity for the E-Cat? I see that
H.H. calculated 14.2 liters, but has there been any confirmed
number out of the Rossi camp?
I only ask, because multiple references have been made to "tons of
cooling water" to quench the reaction during H.A.D.
In reality, the water flowing through the E-Cat (as the heat
exchanger primary-side output) was measured twice:
The first time, it was .91 grams/sec and the second time it was
just shy of 2 g/s.
If the E-Cat were indeed 14.2liters (14.2 kg), the entire contents
of the E-Cat would take 2-4 hours to be completely replaced. All
the while, a "device that generates frequencies" is still running.
When it is turned off, the E-Cat temp begins declining.
Soooo many questions.
Somewhere I think I saw a statement that the new E-cat has 30 liters
water volume. I don't see how that is possible if the dimensions
provided in the NyTeknik report are correct.
I have made changes to my data review in this area. It is located at:

Following are the related sections.
VOLUME CALCULATIONS
The Lewan report says: "The E-cat model used in this test was
enclosed in a casing measuring about 50 x 60 x 35 centimeters."
"After cooling down the E-cat, the insulation was eliminated and the
casing was opened. Inside the casing metal flanges of a heat
exchanger could be seen, an object measuring about 30 x 30 x 30
centimeters. The rest of the volume was empty space where water could
be heated, entering through a valve at the bottom, and with a valve
at the top where steam could come out. "
This gives an external volume of (50 x 60 x 35) cm^3 = 105000 cm^3 =
105 liters. The heat exchanger etc. is (30 x 30 x 30) cm^3 = 27
liters. This should give an internal volume of 105 liters - 27 liters
= 78 liters.
The prior similar E-cat weighed in at 85 kg.
Looking at the open E-cat photo it looks like about (1/9)*30 cm = 3.3
cm is cooling fins. About 50% of the 3.3 cm x 30 cm x 30 = 2.97
liters should be water, giving a total water volume of 78 liters + 3
liters = 81 liters.
NO HEAT TRANSFER TO HEAT EXCHANGER UNTIL 13:22
19:22: "Measured outflow of primary circuit in heat exchanger,
supposedly condensed steam, to be 345 g in 180 seconds, giving a flow
of 1.92 g/s. Temperature 23.2 °C."
This indicates the pump primary circuit flow is probably about 1.92
ml/s, as it was in the Krivit demo. The heat showed up in the
exchanger at about 130 minutes, or 7800 seconds into the run. See
appended graph, or see spreadsheet at:
http://www.mtaonline.net/~hheffner/Rossi6Oct2011.pdf
This means the flow filled a void of (7800 s)*(1.92 ml/s) = 15 liters
before hot water began to either overflow or percolate out of the
device, and thus make it to the heat exchanger.
If overflow started after 15 liters then it would appear 81 - 15 = 66
liters were already present. The device weighed in at 98 kg before
the test and 99 kg after, when the water was drained, making this
impossible.
If the E-cat cold water input is 24°C and 15 liters were input, it
takes (4.2 J/(gm K)) *(15,000 gm))*(76K) = 4.79 MJ to heat the water
to boiling. Looking at the spread sheet this input energy Ein was
indeed reached at about 13:22. This means steam probably reached the
heat exchanger at this time, about 130 minutes into the test.
