Hi Ian,
Sorry, I was spending Chinese new year vocation so that I could not reply it fast. I have looked into your spreadsheet. I have some questions.
1) In my spreadsheet, first row is physical temperature of water. 16 and 85 are minimum and maximum respectively. Tref is fixed to 298.15 K (25 degree) which is stated in TMP006 SBOU017. But in your spreadsheet, Tref is set to 16 and 85 degree. Why? What does Tref mean?
2) In your spreadsheet, C2 is not taken into account. What is impact? I guess it can be ignored.
3) If I use 7.0E-14 as S0, the calculated result is far smaller than physical temperature. For example, in last column, the calculated result is 42 degree. But physical temperature of water is 86 degree. What is the problem?
4) Could you please point out what is wrong with my calculation? How to correct it?
Best Regards,
Luo Sheng
