It shows the first 2.8 hours. As I said, the pump is usually left on all the time. For the purpose of this test it was turned off for a day and the reactor and Dewar were left to cool down. As you see the water temperature climbed after the pump was turned on. After 1.5 hours the terminal temperature was reached, 0.6°C above ambient. It never goes any higher. Other tests have confirmed this. This is the baseline temperature including the pump heat. Mizuno uses this starting temperature and measures to the terminal temperature at the end of the test just before the cell and water temperature begin to decline. If you were to come in first thing in the morning, turn on the pump and immediately turn on the experiment, the pump heat would be included in the excess heat. That would be a problem. However, Mizuno never does that. If the equipment is off he turns it on an hour or two before beginning an experiment. As I said, in most cases he leaves the pump, power supplies and data collection running overnight, as you see in the graphs. - Jed
