Consider a pan placed on an electric range to cook spaghetti. The bottom
section of the pan is 0.5cm thick and has a 20cm diameter. The electric
heating unit consumes 1kW of power during cooking and 80% of it is
transferred uniformly to the pan. Thermal conductivity of the pan is 50
W/mK. If the required temperature to cook spaghetti is 100C, determine
the temperature of the outer surface of the pan.
