My concern is that the exit flow rate is not accurately measured at an input meter when reverse steam pressure is applied at the high temperatures seen. It has not been proven that the input gauge is accurate under this condition.

It would not change the measured energy. 2013/8/12 David Roberson <[email protected]> They checked the metered flow rate in the input side, but did not capture and measure the water exiting the demonstration when steam was being generated. I wish this had been done at least on one occasion.

I worry that since they are using water mains, there could be back pressure from the steam that slowed the flow. I haven't heard this discussed, but then I have been away.

If you doubt that. You can doubt anything. 2013/8/12 Jed Rothwell <[email protected]> Daniel Rocha <[email protected]> wrote: I suppose they did not need to include that enthalpy in the computation shown on the screen, but they should have demonstrated that the outlet temperature was correct and the flow rate was correct, as I described in my "Suggestions for a more effective demonstration." These are key parameters. They need to be confirmed. - Jed -- Daniel Rocha - RJ [email protected] -- Daniel Rocha - RJ [email protected]
