Mechanisms of heat transfer

Heat transfer is an essential discipline in thermal engineering that deals with the transfer, conversion, usability, and creation of heat or thermal energy. Transfer of heat occurs through various mechanisms like conduction, convection, radiation, and change of phases. All these mechanisms have distinct characteristics, but these mechanisms can simultaneously occur in an identical system.

After the sinking of RMS Titanic, US operated the International Ice patrol with the purpose of monitoring the presence and movements of icebergs in the Atlantic and Arctic oceans. Once, they observed a unique tabular iceberg in a form of a rectangle (250 km x 50 km x 300 m). The sun is the only source of heat and the ice absorbs a mean of 98 J/m2-s, 12.5 hrs per day. The exposed area for heating is 250 km x 50 km and the density is 920 kg/m3. How much heat does the exposed heating area absorb per day? Express answer in J/day and in scientific notation with four decimal places. To input: if the answer is 4.7834x1025, input 4.7834e25.

The exposed area for heating is 250 km x 50 km and the density is 920 kg/m3. The latent heat of fusion/melting of ice is 333.5 J/kg. A year has 365 days. How many years would it take to melt the iceberg solely by heat from the sun? Express answer in two decimal places. Hint: To get time, divide the heat of melting by the heat provided by the sun.
