H. W.: The cost of a 2-core feeder cable, including installation is (90 a + 20) per meter and the interest and depreciation charges are 10 per cent. The cable is 2 km in length and cost of energy is 4% per unit. The maximum current in the feeder is 250 A and the demand is such that the current copper loss is equivalent to what would be produced by the full flowing for 6 months. If the resistance of a conductor of 1 square cm and 1 km length is 0.173 Q, calculate the most economical cross-sectional area.
