Question

What is deltaG for the throttling step in kJ/kg?

Superheated steam at 90 bar, 625 °C (State 1) undergoes a 3-step process: (i.) First, it is throttled by a valve to 16 bar (State 2). (ii.) Next, it is isochorically cooled to a saturated vapor (State 3). (iii.) Finally, it is compressed isentropically back to the original 90 bar pressure (State 4). TE
