A rigid vessel of volume 0.02 m3 contains 0.054 kg of steam at an initial pressure of 4 bar. Heat is supplied to the steam from an external source. Calculate (i) the initial quality of the steam, (ii) the temperature and quality of the steam when the pressure becomes 4.5 bar, (iii) the pressure of the steam when it is just dry saturated, and (iv) the temperature when the pressure reaches 7 bar. Indicate the process on a P-V and T-V diagram for water. [Answers: (i) 0.8, (ii) 147.9°C, 0.894, (iii) 5.07 bar, (iv) 298.4°C]
