Equation for satured steam curve
Equation for satured steam curve
(OP)
Dear all,
If have this equation for saturated steam temperature as function of the steam pressure.
Tsat = 100*P^0.25
T [Celcius]
P [bar]
Results are reasonable but I need more accuracy.
Does anybody have a more accurate equation for me?
Thanks for helping!

I haven't used the correlation you shown but based on it's pretty basic coefficients, you should be able to get a better match pretty easy.

I've put together a simple Excel spreadsheet based on tables in ENCYCLOPEDIA OF CHEMICAL PROCESSING & DESIGN written by JOHN McKETTA of University of Texas. The results look pretty good to me. If you want, post your email address.

Thanks for the offer, I already took the equations from IAPWS-IF97 and results look pretty accurate when compared with steam tables:
