Equation for satured steam curve 2

[CARF]

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!

You can download an Excel addin for free:

This has the 1997 steam table equations.

Sorry, I don't have an equation but I've used the referenced above add-in and have been happy with it. If you need a standalone equation, I'd develop a correlation in Excel.

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.

Hi Cymro,

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