Subject: Re: [Vo]:Something more on the steam
You are right you would not use it to measure the enthalpy of hot water. Bingo!
Wet steam is, partly, hot water! It is not a uniform material, it will separate
out into hot water and water vapor. I don't think the probe is measuring the hot
water at all.
If they have already determined that the steam exiting the reactor is
dry by sight and by feel, it is appropriate to measure the ratio of water-gas to
air-gas with a suitable probe.
But it's pointless.
We know, a priori, that after the system's been in operation for a short
while, all air has been flushed from the cooling system and the stuff
coming out is essentially 100% water (whether gaseous or liquid is a
different question).
Some amount of CO2 and assorted other gases could be dissolved in the
input water but certainly not enough to worry about.
