,642 CHAPTER 23 1958 Guide y based on the change in volume from 0 F to 91 F. From Table 7, determine w = 62.5 lb per cu ft at 0 F, and w = 60.5 lb per cu ft at 91 F. From Table 1, Chapter 26, 10,000 ft of 1-in. IPS contains 44.9 gal. Allowing another 15 gal for heat exchanger' headers, etc., assume the system contains 60 gal. Then the expansion would be -- 2 65q! M-5*. 2.48 gal. A quick approximation of required head can be obtained from Fig. 20. At 91 F, the oil has a viscosity of 4.92 X 10"* ft sq per sec or 35 SSU. Enter Fig. 20 at 35 SSU and rise to the 12 gpm curve, read h = 12.5 ft per 100 ft, then ht -- 12.5 X -- = 37.5 ft, which agrees fairly well with the 37.9 ft obtained by the Equation 23.
