In order not to damage the resistance in the kettles, the difference between the temperature of the heater and the fluid should not exceed 25 °C. If the heat transfer area between the fluid and the heater is 78.5 cm² and the heat transfer coefficient is 400 W/m².K, find the maximum allowable power of the heater in order to boil water?
