QUESTION 1 Complete the following table for H2O (water). Show all steps taken in order to fill the blanks. Sketch states (a) to (e) on a (only one) T-D property diagram. State T(C) P (kPa) u (kJ/kg) Quality, x Phase Description a 400 1450 b 220 Saturated vapour C 210 2500 d 2000 2773.2 e 3000 0.0000 *Please copy again the table with the answer obtained in the answer paper. QUESTION 2 A piston-cylinder device initially contains 0.4 m of air at 100 kPa and 80C. The air is now compressed to 0.1 m in such a way that the temperature inside the cylinder remains constant. i) Sketch the schematic diagram of the device before and after the compression process. ii) Determine the mass of air, kg. iii) Calculate the final pressure, kPa. iv) Show the compression process on a P-D property diagram and label clearly all the pressure, volume and temperature. Take for air, R = 0.287 kJ/kg.K
