= weight of ice-covering 1 ft. Long, 1 sq. In. In sectional area (12 cu. In. At 0. 0321 Ib. Per cubic inch), value of x in the formula, P, = xv z d = pres- sure in pounds per square foot: x = 0. 0002 when v = miles per hour, and d = diameter of wire, in inches. The curves in the diagram are applicable within the following limits: Diameter of cable; from No. 2 to No. 000000 B. & S. G. Diameter of wire; from No. 12 to No. 0000 B. & S. G. Sectional area of wire; from 6530 to 212, - 000 circular mi...ls. Ratio (k = D/d) between the diameter of the ice-coating and that of the wire, from 1 to 10. Wind-velocity, v; from 20 miles per hour to 120 miles per hour. Value of ratio m; from 1 to 17. Data necessary for using Chart No. 1 (a) The gauge number (B. & S. G. ) or the diameter, d, or the sectional area, s, of the wire; (b) the wind-velocity, v (in miles per hour) ; (c) the ratio, k, between the external diameter of the ice-coating and the diameter of the conductor. Directions Find the point corresponding to the number (B.
