2006 Spring Thermodynamics Homework #7 Solutions 1. Refrigerant -134a as saturated vapor at 0.5 MPa is isentropically compressed by a compressor in a refrigeration plant to 1.2 MPa. Determine the enthalpy change for the process and the final fluid phase. Solution: Substance Type: Compressible (R-134a) Problem Type: Process(Isentropic) State 1 State 2 T2 = 49.3 C T1 = 15.71 C P1 = 0.5 MPa P2 = 1.2 MPa h1 = 259.30 kJ/kg h2 = 277.4 kJ/kg s1 = 0.9240 kJ/(kgK) s2 = 0.9240 kJ/(kgK) phase: sat.vap. phase: sup.vap. Italicized values are from R-134a tables, bold values are calculated. ME 201 At state 1 we know the pressure and that we have saturated liquid, so that the state is fixed. Going to the saturation pressure table, Table A-12, we find T1 = 15.71 C, s1 = 0.9240 kJ/(kg K), h1 = 259.30 kJ/kg At state 2 we know the pressure and that we have an isentropic process or s 2 = s1 = 0.9240 kJ/(kg K) To determine the fluid phase, we go to the saturation pressure table at 1.2 MPa and find s f = 0.4244 kJ/(kg K) and s g = 0.9130 kJ/(kg K) Since s2 > sg, we have a superheated vapor at state 2. Going to the superheat tables, Table A-13, we find after interpolating T2 = 49.3 C, h 2 = 277.4 kJ/kg Our enthalpy change is then h = h 2 - h1 = 277.4 - 259.3 = 18.1 kJ/kg 1 ME 201 Thermodynamics Spring 2006 2. What is the quality and internal energy of 0.1 lbm of steam contained in a 1.3 ft3 container at a temperature of 233 F? Solution: Substance Type: Compressible (steam) Problem Type: State State 1 T1 = 233 F v1 = 13 ft3/lbm u1 = 822.2 kJ/kg phase: 2 phase mixture x = 0.704 Italicized values are from steam tables, bold values are calculated. we Since know the temperature and the specific volume can be calculated, the state is fixed. The specific volume is given by V 1.3 v1 = = = 13 ft 3 / lbm m 0.1 Going to the saturation temperature table , Table A-4E, we interpolate to find v f = 0.0016864 ft 3 /lb m and v g = 18.46 ft 3 /lb m Since vf < v1 < vg, we must have a two phase mixture with 13 - 0.0016864 x1 = = 0.704 18.46 - 0.0016864 The internal energy is then given by u = u f + x u fg = 201.34 + (0.704)(881.9) = 822.2 Btu/lbm 3. Air enters the combustion chamber of a jet aircraft engine at 800 kPa and 600 K and exits at 2200 K. Since an ideal combustion chamber is isobaric, determine the entropy change and exit specific volume. Solution: Substance Type: Ideal Gas (air) Problem Type: Process(Isobaric) State 1 State 2 T1 = 600 K T2 = 2200 K P1 = 800 kPa P2 = 800 kPa 3 v1 = 0.215 m /kg v2 = 0.7894 m3/kg 1= 2.40902 kJ/(kg K) 2 =3.9191 kJ/(kg K) Italicized values are from air tables or ideal gas law, bold values are calculated. 2 ME 201 Thermodynamics Spring 2006 At state 1 we know both the temperature and the pressure, so that the state is fixed. Then from the air tables, Table A-17, we find 1 = 2.40902 kJ / (kg K) and using the ideal gas law RT1 (0.287)(600) v1 = = = 0.215 m3 / kg P1 800 At state 2 we know the temperature and that the process was isobaric, thus P2 = P1 = 800 kPa Our state is now fixed and from the air tables, Table A-17, we find 2 = 3.9191 kJ/(kg K) and using the ideal gas law RT2 (0.287)(2200) v2 = = = 0.789 m3 / kg P2 800 Then P s = 2 - 1 - R ln 2 P1 800 = 3.9191 - 2.40902 - (0.287)ln 800 = 1.51 kJ/(kg K) 3
