Задача id16544

Silvering of the plates is carried out at a current density of j = 0.5 A/dm2, and during the time t = 5 hours a mass of m = 2 kg of silver is released. Find the voltage at the terminals of the electrical network if the voltage at the terminals of each bath is U0 = 5 V and silvering is carried out in n = 60 baths connected in two parallel groups of 30 baths connected in series in each group. Find the energy consumption (in hectowatt hours) during an hour of silvering. Efficiency settings h = 90%. Electrochemical equivalent of silver k = 1.118·10-6 kg/C.
