a) Explanation Write energy balance equation for a closed system. E in − E out = Δ E system − Q out = m c p ( T 2 − T 1 ) water Q out = m c p ( T 1 − T 2 ) water (I) Here, temperature at inlet and outlet condition is T 1 and T 2 respectively, energy transfer at inlet and outlet condition is E in and E out respectively, and total mass of water is m . Write the expression for the mass of water. m = ρ V (II) Here, Volume of a water is V . Conclusion: Refer to Table A-3, “properties of common liquids, solids, and foods”, obtain the following properties of the water. ρ = 997 kg / m 3 c p = 4.18 kJ / kg ⋅ ° C Substitute 0.350 m 3 for V , and 997 kg / m 3 for ρ in equation (II) b) To determine The exergy destroyed during the process.
