1. The galvanizing of iron sheet can be carried electrolytically using a bath containing zinc sulfate solution. The sheet is made the cathode, and a graphite anode is used. Calculate the cost of electricity required to deposit 0.49 mm layer of zinc on both sides of an iron sheet 2.0m wide and 80m long if the currentis 30 A, the voltage is 3.5 V, and the energy efficiency of the process is 90%. Assume the cost of electricity is Php 12.50 per kilowatt-hr. The density of zinc is 7.1g/cm?.
