Using the appropriate table, determine the indicated property. In each case, locate the state on sketches of the T-v and T-s diagrams. Include the vapor dome on the diagram.
a) Water at p = 0.20 bar, s = 4.3703 kJ/kg.K. Find h, in kJ/kg.
b) Water at p = 10 bar, u = 3124.4 kJ/kg. Find s, in kJ/kg.K.
c) Refrigerant 134a at T = -28oC, x = 0.8. Find s, in kJ/kg.K.
d) Ammonia at T = 20oC, s = 5.0849 kJ/kg.K. Find u, in kJ/kg.
Please explain which table you use, and any calculations (if needed) to find the values on the table.
