0 O file:///C:/Users/MEGA/Downloads/Cengel.%20Heat%20and%20mass%20Transfer%20F FIGURE P10-20 10-21 Water is boiled at sea level in a coffeemaker equipped with a 30-cm-long, 0.4-cm-diameter immersion-type electric heating element made of mechanically polished stainless steel. The coffeemaker initially contains 1 L of water at 14°C. Once boiling starts, it is observed that half of the water in the cof- feemaker evaporates in 32 min. Determine the power rating of the electric heating element immersed in water and the surface temperature of the heating element. Also determine how long it will take for this heater to raise the temperature of 1 L of cold water from 14°C to the boiling temperature.
