In this case there is only one problem/question. 1L per second i.e. 15.65 gpm is an incredibly high flow for a tap and for the water feeding tubes. Perhaps a garden hose could do it. It seems it was a surprise- the 130kW heat peak and this was quenched with the maximum available flow. No flowmeter was installed. Anyway I have performed many industrial tests/experiment in the chemical industry and we had an axiomatic saying- 1 test is no test, 1 result is no result. Why all the other teste were performed with water to steam? And why the enthalpy of the steam was not measured? Peter
