Answer: Using u?h Data Using the tables for water,

QUESTION:

Using the tables for water, determine the specified property data at the indicated states. In each case, locate the state by hand on sketches of the p-v and T-v diagrams.

(a) At \(p=20 \mathrm{lbf} / \mathrm{in}^2, v=16 \mathrm{ft}^3 / \mathrm{lb}\), find T in \({ }^{\circ} \mathrm{F}\) and u in \(\mathrm{Btu} / \mathrm{lb}\).

(b) At \(T=900^{\circ} \mathrm{F}, p=170 \mathrm{lbf} / \mathrm{in}^2\), find v in \(\mathrm{ft}^3 / \mathrm{lb}\) and h in \(\mathrm{Btu} / \mathrm{lb}\).

(c) At \(T=600^{\circ} \mathrm{F}, v=0.6 \mathrm{ft}^3 / \mathrm{lb}\), find p in \(\mathrm{lbf} / \mathrm{in}^2\) and u in \(\mathrm{Btu} / \mathrm{lb}\).

(d) At \(T=40^{\circ} \mathrm{F}, v=1950 \mathrm{ft}^3 / \mathrm{lb}\), find p in \(\mathrm{lbf} / \mathrm{in} .^2\) and h in \(\mathrm{Btu} / \mathrm{lb}\).

(e) At \(p=600 \mathrm{lbf} / \mathrm{in.}^2, T=320^{\circ} \mathrm{F}\), find v in \(\mathrm{ft}^3 / 1 \mathrm{~b}\) and u in Btu/lb.
