Heat transfer and entropy change for water vaporizing at 10 MPa

[Nick Goodson]

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

The problem does not specify initial temperature.
If you are free to assume, you could use steam tables per unit mass for the vaporization process only.
