The world's most active volcanoes, such as the Kilauea volcano in Hawaii, can disgorge about 5.00 X 105 m3 of 1100°C lava per day. What is the rate of heat transfer (in MW) out of the earth by convection, if this lava has a density of 2800 kg/m3 and eventually cools to 25°C? Assume that the specific heat of lava is the same as that of granite.
