I am way behind on reading. I hope this is not redundant.
It appears the same pump is being used 6 Oct 2011 as in all the prior
tests. See:
http://www.nyteknik.se/nyheter/energi_miljo/energi/article3284823.ece
I wonder what the 4 pumps are for? Eventually pumping water into the
heat exchanger? That would be excellent, if the flow rate could be
reduced, and highly controlled. It appears there is tubing on the
pumps. Could the pumps have been used in an earlier test and discarded?
At 2:37 the old yellow pump can be seen. It appears it was used to
pump the E-cat input water as usual.
At 0:21 in video "at this point we have been going for several hours".
"One hour or so ago we went into self sustained mode."
At this point in the Lewan video I counted 41 strokes per minute of
the pump. Based on Matiia Rizzi's comments below, that is a maximum
flow rate of (41 str/min)*(2 ml/Str)*(1 min)/(60 sec) = 1.37 ml/sec,
or 4.9 liters per hour.
I wonder how a pump with a maximum flow rate of 12 liters/hr could
pump 15 liters/hr?

Mr. Rossi,
Could you tell the primary flow rate of the peristaltic pump?
Unfortunately this was not documented.
From this we could get an optimistic upper limit for the energy
generated, if we assume all water was vaporized.

Dear Peter Heckert:
Good question.
The primary circuit flow rate has been 15 kg/h of water.
Warm Regards,
A.R.

And the water flow can’t be 7 liter/h since the pump is pumping
every 2.5-3 seconds, so the true water flow is lower than 3 liter/h
LMI P18 pump has a maximum flow of 12 l/h at 100 strikes/minutes.
With 25 strikes/minute is (maximum) 3 l/h. It can be lower than 3
liter/h.

Again, if you write “7 l/h flow” you are talking about the test
done in june, with Krivit.
In june, there wan’t a weight scale, only a “Rossi said” that he
controlled the flow by weighting it. But is a “Rossi said”.
What we really know is the pump used, an LMI P18, and we know that
the maximum flow is 12 l/h at 100 strokes/min.
Since you can hear in Krivit video that the pump is stroking every
2.5-3 seconds, according to the manual the maximu flow rate
achievable with 25 strokes/min is 3 liter/h. That’s a fact, not a
“Rossi said”.

It’s a dosimetric pump.
In every stroke it can inject a maximum volume of 2ml of water
(volume is regulable)
It’s regulable from 20 to 100 strokes/minute.
So with a 100 strokes/min and a volume of 2ml, the pump is running
witha flow of 12 liter/h.
With 25 strokes/min, the pump is running up to 3liter/h (but it can
be lower since volume is adjustable).
kind regards,
Peter
