QUESTION:

Determine the values of the specified properties at each of the following conditions.

(a) For Refrigerant 134a at \(p=140 \mathrm{lbf} / \mathrm{in}^2\) and \(h=100 Btu / \mathrm{lb}\), determine T in \({ }^{\circ} \mathrm{F}\) and v in \(\mathrm{ft}^3 / \mathrm{lb}\).

(b) For ammonia at \(T=0^{\circ} \mathrm{F\) and \(v=15 \mathrm{ft}^3 / \mathrm{lb}\), determine p in \(\mathrm{lbf} / \mathrm{in}.^2\) and h in \(\mathrm{Btu} / \mathrm{lb}.

(c) For Refrigerant 22 at \(T=30^{\circ} \mathrm{F}\) and \(v=1.2 \mathrm{ft}^3 / \mathrm{lb}\), determine p in \(\mathrm{lbf} / \mathrm{in.}^2\) and h in Btu/lb.
