calculated for any given condition as follows: Example. Given a 3 line 100 ft. in length, carrying steam at 80 lb. gage, and covered with oneinch of 85 per cent magnesia having an insulating efficiency of 83.5 per cent as given by Table 26. Theplant operates 10 hours per day for 300 days per year,… … 580 HEATING AND VENTILATION The heat sa\-ed in this line with this covering in place is, assuming a low value for the coefBcieutat 801b., and taking K = 2.65 B.t.u. per hr., H = 2.65 X ( 324 - 65) X 0.835 = 575 B.t.u. per sq. ft.perhr. Hence, for a year of 300 days at 10 hours per day the heat loss…
