Hello everybody, would somebody please put me on the right track to answering this question?

'Consider water undergoes a heat transfer

at constant pressure of 10 MPa and

changes from liquid to steam. Find the

entropy of the system (sfg) as well as the

heat transfer per unit mass in this

process?'

Is this just looking at steam tables and working per unit mass?

I'd appreciate any help

Thanks

Sorry, of course, I knew that !!!

Thanks 😊

Hey Nick, actually you are looking at superheated steam table. Superheated steam table are used when steam is heated even beyond it gets converted into vapor phase. You should look at "Saturated water - Pressure table" instead. It should be on the pages just before superheated table. check out entropy values at 10 MPa pressure. I hope you find this useful.
