Electromagnets that produce large magentic fields use water cooling to prevent excessive heating of the magnet's coils. A large laboratory electromagnet has a current equal to 106 A when a voltage of 240 V is applied to the terminals of the energizing coils. To cool the coils, water at an initial temperature of 14°C is circulated around the coils. How many liters of water must circulate by the coils each second if the temperature of the coils is not to exceed 49°C?
