Alan, excellent work again. Considering Akira's temperature graph, we can take that draining took about 5-7 min. In the beginning pressure was 210 kPa or 122°C. But it is needed to take into consideration, that valve was opened slowly. In the end of video, valve was only half open.

It is not anymore just an assumption, but data supports the idea. –Jouni 2011/9/21 Alan J Fletcher <a...@well.com>: > I just ran the calculations for draining a 30L eCat through a 0.25 cm radius > tap. > > http://lenr.qumbu.com/rossi_ecat_sep11_f.php > > The drain-time says 2 Bars !!!!! > > 6.
