Answer:
<u>Total Mass of Conductors = 19913661.3 kg</u>
Explanation:
The total length is given as:
Total Length = 845 mi
Converting it to ft:
Total length = (845 mi)(5280 ft/1 mi)
Total length = 4,461,600 ft
The weight of one conductor per unit length is:
Mass of one conductor per unit length = 2460 lb/1000 ft
Mass of one conductor per unit length = 2.46 lb/ft
Since there are 4 conductors, therefore, total weight of all conductors per unit length will be:
Mass of all four conductors per unit length = 4 x 2.46 lb/ft
Mass of all four conductors per unit length = (9.84 lb/ft)(0.453592 kg/1 lb)
Mass of all four conductors per unit length = 4.463 kg/ft
Therefore, total mass of conductors in the line will be:
Total Mass of Conductors = (Mass of all four conductors per unit length)(Total Length)
Total Mass of Conductors = (4.463 kg/ft)(4,461,600 ft)
<u>Total Mass of Conductors = 19913661.3 kg</u>
