enthalpy

There are tables with all values I have them not any more but if you find one you get all data you ask for. Of course you will have to interpolate since the values are not given exactly for the parameter values you mention. But this you know how to do.

You can go to the following link and use the calculator to obtain the enthalpy of your feedwater.

Good luck, and let me know if I can be of further assistance.
