Chapter 6, Problem 6.3(choose chapter or problem)
Using the appropriate table, determine the indicated property. In each case, locate the state on sketches of the T– and T–s diagrams.
(a) water at p = 0.20 bar, \(s=4.3703 \mathrm{\ kJ} / \mathrm{kg} \cdot \mathrm{K}\). Find h, in kJ/kg.
(b) water at p = 10 bar, u = 3124.4 kJ/kg. Find s, in \(\mathrm{kJ} / \mathrm{kg} \cdot \mathrm{K}\).
(c) Refrigerant 134a at \(T=-28^{\circ} \mathrm{C}\), x=0.8. Find s, in \(\mathrm{kJ} / \mathrm{kg} \cdot \mathrm{K}\).
(d) ammonia at \(T=20^{\circ} \mathrm{C}, s=5.0849 \mathrm{\ kJ} / \mathrm{kg} \cdot \mathrm{K}\). Find u, in kJ/kg.
