Your comment is appropriate Jed. I am still attempting to reconcile the flow rate and thermocouple reading so that they make some logical sense to me. I plan to take a second look at the simulation where the output power is forced to match the measured rate seen by Mats by some form of temperature reading adjustment. If the output power is reduced, I may find that overflow can occur after enough time elapses. Mats second flow measurement suggests overflow near the end of the test. I do not know whether or not any of these ideas will pan out, but they need to be examined. The truth is out there!

He very carefully measured a rate of .9 grams per second being careful not to disturb the plumbing. This value coupled with the assumed leakage rate (2 kilograms per hour or .55555 grams per second) adds up to approximately 1.45 grams per second input. I do not think this indicates a flow rate of 1.45 g/s. I think the power level was much higher previous to this, and the water level in the box was falling. During the 6 min. that Lewan measured the flow rate of 0.9 g/s, all of that water was condensate from steam that left the box. None of it was overflow. During this 6 min. period (and before and after) the water level was rising and it might have overflowed eventually, if the power had remained low. - Jed
