A rigid closed tank having a volume of 2 m3 contains 0.1 m3 of saturated liquid water and 1.9 m3 of saturated water vapor at 100 kPa. Heat is transferred to the tank until the final tank pressure reaches 2 MPa. Following data for water is given: At 100 kPa: vf = 0.001043 m3/kg, vg = 1.694 m3/kg, uf = 417.33 kJ/kg, ug = 2506.06 kJ/kg At 2 MPa: vf = 0.001177 m3/kg, vg = 0.09963 m3/kg, uf = 906.42 kJ/kg, ug = 2600.26 kJ/kg The magnitude of heat transfer in this process is
- A. 34670 kJ
- B. 55842 kJ
- C. 67906 kJ
- D. 77470 kJ
Answer: D. 77470 kJ
