Applying the Exergy Balance: Closed Systems

Water vapor enters a valve with a mass flow rate of 2 kg/s at a temperature of 320oC and a pressure of 60 bar and undergoes a throttling process to 40 bar.

(a) Determine the flow exergy rates at the valve inlet and exit and the rate of exergy destruction, each in kW.

(b) Evaluating exergy at 8.5 cents per kW · h, determine the annual cost, in $/year, associated with the exergy destruction, assuming 8400 hours of operation annually.

Let T0 = 258C, p0 = 1 bar.
