PROBLEM 28P

Imagine that your dog has eaten the portion of below Table 1 that gives entropy data; only the enthalpy data remains. Explain how you could reconstruct the missing portion of the table. Use your method to explicitly check a few of the entries for consistency. How much of below Table 2 could you reconstruct if it were missing? Explain.

Table 1: Properties of saturated water/steam. Pressures are given in bars, where 1 bar = 105 Pa ≈ 1 atm. All values are for 1 kg of fluid, and are measured relative to liquid water at the triple point (0.01°C and 0.006 bar). Excerpted fromKeenan et al. (1978).

T (°C)	P (bar)	Hwater (kJ)	H steam (kJ)	S water (kJ/K)	S steam (kJ/K)
0	0.006	0	2501	0	9.156
10	0.012	42	2520	0.151	8.901
20	0.023	84	2538	0.297	8.667
30	0.042	126	2556	0.437	8.453
50	0.123	209	2592	0.704	8.076
100	1.013	419	2676	1.307	7.355

Table 2: Properties of superheated steam. All values are for 1 kg of fluid, and are measured relative to liquid water at the triple point. Excerpted from Keenan et al. (1978).
