The SI versions of these figures areprovided below and at right.p. 19.2, Table 1. For the rightmost four columns, the headingsshould be +1500, 1500, +2500, and
4、 2500 Pa.p. 25.1, Fig. 1. Point E was omitted. The correct figure appearsbelow right.p. 26.2, Eq. (2a). In the rightmost fraction, change msto me.p. 26.4, 1st col., top. Units for the results for w2and w4should bekg/kg of dry air.p. 40.19, Table 1. In fifth column, change value in row 6 to 0.0345,an
5、d in row 7 to 0.0334.p. 41.3, Fig. 3. Replace parts B and C of the graphic with the hori-zontal polymer tube shown on p. A.2.p. 44.8, Table 1. In both equations for flow and pressure, change theminuses to equals signs.p. 51.8. In the first column, change “44 153 kWh” to “44 513 kWh”in two places: th
6、e first line, and in the paragraph before Eq. (4). In thesecond column, second paragraph, equation for TES tank volume,change “44 153” to “44 513” and add “ 0.9” after “998 kg/m3.” Theresult remains 4738 m3.p. 51.13, Table 4. For hour 6, Storage should be 1400 kW.p. 51.24, Fig. 25. The bottom right
7、line should have the dischargearrow pointing to the left, and the charge arrow pointing to the right.The corrected figure is shown on p.

Above Eq. (38), change “td( p, w)” to “td( p, W ).”p. 1.10, 1st col
9、 In the table for Situation 2, 3rd line, Comments col-umn, change “td” to “t.”p. 4.21, Solution for Example 10, starting in 3rd para. Compute hiusing Eq. (T8.5a). For cpw, units should be J/(kgK). Delete fsand itsvalue. Nudshould be 248.3, and hishould be 7087 W/(m2K). Com-pute housing Eq. (T9.10a)
10、 Change Ra to 74 574, Nu to 7.223, hoto3.65 W/(m2K), and the equation for hotto 3.65 + 4.3 =7.95 W/(m2K). Change the last paragraph in the example as follows:Solving for domakes the left side of Equation (42) equal to the rightside, and gives do= 0.040 03 m. Now, using the new value of 0.040 03 mfo
11、r the outer diameter, the new values of hoand hotare 3.86 W/(m2K)and 8.20 W/(m2K), respectively. The updated value of dois 0.044 03 m.Repeating the process several times results in a final value of do=0.047 17 m. Thus, an outer diameter of 0.045 m (corresponding to aninsulation radial thickness of 1
12、2.5 mm) keeps the outer surface tempera-ture at 24.1C, higher than the dew point. Another method is to useEquation (42) to solve for tofor values of docorresponding to availableinsulation thicknesses and using the insulation thickness that keeps toabove the dew-point temperature.p. 9.19, 1st col. Fo
13、r Eq. (71), remove the minus sign before “(tsk34).” In the following definitions, add that tbsetshould be 36.49C. InEq. (72), change the minus in the denominator to a plus. In the para-graph below Eq. (74), blshould be 1 kg/L.p. 9.23, after Eq. (83). WCI should be multiplied by 1.163 to getW/m2.Ch.

Data for elements 2 and 5 and the total should be asfollows: p. 27.3, 2nd col. For element 1, wind speed should be 6.7 m/s.p
15、 27.4, 1st col., Example 3. In the elements table, wind speed forelement 1 should be 6.7 m/s. After the equation for UAssembly, change“300 mm” to “600 mm.”p. 27.4, 1st col., Example 4. On fourth line, face shell thicknessshould be 32 mm. In the Solution, wind speed for Roshould be6.7 m/s.p. 27.4, 1
