The values of S per pound of condensate were calculated within therange of temperatures shown in Table I using a value of U - 300. These valuesare shown in Table V and are plotted in Pig. 6.

U. OF 11 S. 5. FORM 3 22. 5, Considering a 1000 k. w., unit using 20, 000 pounds of steam perhour. If (T2 - Ti) * 15 degrees and (l^ - T2) = 17 degrees we find fromPig. 5 that Tm is 23 and from Pig. 6, S is 0.15. This gives 20, 000 x 0.15equals 3000 square feet of surface. A ratio of from 2 1/2 to 4 has been as-sumed by certain menufacturers for ascertaining the value desired, arnroximate- iy. The square feet of surface is determined by multiplying the k. w.capacity by the above factor. Thus assuming 3 as an average we have 3 x 1000equals 3000 square feet. 23. CHAPTER V DISCUSSION OP PUMPS 1. Condenser pumps may be divided into two classes: fa) wet air pumps,and (b) dry air rmmps. The former handles both water and air, and the later airalone. Ordinary jet condenser wet air pumps handle simultaneously the circulat-ing water, condensed steam, entrained air, and vapors. The surface condenserwet air nump handles the condensed steam, air, and vapors only. Wet air pumpsmay be driven by the
