In the September report, they drain the water in the E-Cat through the fill port, and 22,400 grams are expelled. This seems to be at or near overflowing, based on the collected water; Also, the E-Cat weighed about a kg more than it started at (this is presumably water retained below the level of the input valve). This puts E-Cat water capacity in September at ~23,400 kg (23.4 litres). Of course, for this to apply to October's test, we are stuck assuming that all of the "wafers" were in place in both demonstrations. It sounded as though the reactor cores were contained in a shell inside of the reactor, but this remains unclear. We cannot determine October's water quantity without more information. Back to flow rates. We know that in the Sept test, the pump dropped from ~4.38g/s when disconnected, all the way down to 3.07g/s during operation. But, the 4.38g/s exceeds the manufacturer's specified range, so this rate is unclear. We know it was run below its highest rate in the October test, because it is sped up for "quenching" or "cool down". Since the pump flow varies based on back pressure, and input flow was not metered, we cannot determine October's flow rate into the E-Cat. The pump displacement and pump speed are adjustable. The sound in the video can indicate pump speed, but not displacement.
