The heat is computed by measuring the amount of water converted to steam. The steam was just over 100 deg C at 1 atm. Therefore, the amount of energy is what it takes to heat the water to boiling plus what it takes to vaporize it. In the January 14 steam test output was ~12 kW, not ~17 kW. ~12 kW is what it takes to heat and vaporize 5 g of water per second. 17 kW was how much they measured in the Feb. 10 liquid water test, during most of the test. The displacement pump was used in the steam tests but not the Feb. 10 liquid water test. I believe you set that pump to whatever speed you want, up to some limit.

No, he adjusts the power. He did not change the flow rate in any test. You can tell the flow rate did not change because the pulsing sound of the pump is at the same rate the whole time. You can tell they measured the flow correctly because they used a weight scale, which is the most reliable method. - Jed
