P-h diagram for superheated steam?
I need to plot a P-h diagram for superheated steam expanding in a nozzle.I know the graph but I need to make sure whether the constant entropy lines are curved or they're straight line.I mean the constant entropy lines of the P-h graph itself not the process.

Referring to the Mollier Diagram for steam and to the Keenan and Keyes Temperature /Entropy Chart for Steam I see that there the entropy lines are vertical on both and the constant enthalpy lines are not.
So, on a P/H diagram the enthalpy lines will be vertical and the entropy lines will be curved.

they are curved, try seeing graphs of refrigeration cycles. :)
