Did you consider that for the first minute, valve was opened only as
little as it can be to be open at all. Later it was opened some more,
but not even then it was fully open. Therefore I think that we can
call this thing to 200 kPa pressure figure. If someone really did even
doubt that, because th

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.
