For each case, determine the specified property value and locate the state sketches of the p–υ and T–υ diagrams.
1. For Refrigerant 134 a at T = 160°F, h = 127.7 Btu/lb. Find υ, in ft³/lb.
2. For ammonia at T = 160°F, p = 60 lbf/in.² Find u, in Btu/lb.

before we can answer, we have to see the choices that are printed there with the question.   that's the only way we can point you to the correct one.
