Conventional large electromagnets use water cooling to prevent excessive heating of the magnet coils. A large laboratory electromagnet draws 100 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 15oC is circulated through the coils. How many liters per second must pass through the coils if their temperature should not exceed 50^oC?
