Superheated water vapor enters a valve at 3445 kPa, 260oC and exits at a pressure of 551

Question:

Superheated water vapor enters a valve at 3445 kPa, 260oC and exits at a pressure of 551 kPa. Determine
(a) the specific flow exergy (ψ) at the inlet and exit and
(b) the rate of exergy destruction in the valve per unit of mass. Let T0 = 25o, p0 = 1 atm.
