As shown in the figure, two kilograms of water undergo a process from an initial state where the water is saturated vapor at 120°C, the velocity is 30 m s-1, and the elevation is 6 m, to a final state where the water is saturated liquid at 10°C, the velocity is 25 m s-¹, and the elevation is 3 m. Determine in kJ, (a) the exergy at the initial state, (b) the exergy at the final state, and (c) the change in exergy. Let T = 25°C, p = 1 atm, and g = 9.8 m s-². Answer: (a) E₁ = = 1000.1 kJ (b) E₂ = 3.9 kJ (c) AE = -996.2 kJ 6 m - Saturated vapor at 120°C ▷ 30 m/s 3 m Saturated liquid at 10°C 25 m/s Po = 1 atm, To = 25°C, 8=9.8 m/s² As shown in the figure, two kilograms of water undergo a process from an initial state where the water is saturated vapor at 120°C, the velocity is 30 m s-1, and the elevation is 6 m, to a final state where the water is saturated liquid at 10°C, the velocity is 25 m s-¹, and the elevation is 3 m.
