Applying the Exergy Balance: Closed Systems

Figure P7.88 and the accompanying table provide the schematic and steady-state operating data for a flash chamber fitted with an inlet valve that produces saturated vapor and saturated liquid streams from a single entering stream of liquid water. Stray heat transfer and the effects of motion and gravity are negligible. Determine (a) the mass flow rate, in lb/s, for each of the streams exiting the flash chamber and (b) the total rate of exergy destruction, in Btu/s. Let T₀ = 77^oF, p₀ = 1 atm.
