A building window pane that is 1.68 m high and 1.12 m wide is separated from the ambient air by a storm window of the same height and width. The air space between the two windows is 0.06 m thick. If the building and storm windows are at 20 and -10°C, respectively, what is the rate of heat loss by free convection across the air space, in W?

PROBLEM 1Consider an adult human standing in the centre of a closed room. The air and room’swalls, ceiling and floor surrounding the being are at a temperature of 25oC. Assume forthe adult body a temperature of 37oC, a surface area of 1.7m2, an emissivity of 0.95 andthe heat transfer coefficient of 6 W/m2K for natural convection between the air and thebody. Question:(a) Describe the modes of heat transfer between the adult human and theirsurroundings. What are some assumptions that must be made before calculatingthe heat transfer rates?(b) Determine the total rate of heat transfer from the adult into their surroundings.

In the arctic sea, the ice sheets are melting. Let's calculate the temperautre distribution in one such ice sheet. The sheet is 2 m thick. Under the sheet there is ice-water mixture and it can be assumed that the temperature of the bottom surface of the ice sheet is approximately 0°C. Air at -20°C is blowing above the sheet. The convection coefficient of air is 15 W/m².K. The thermal conductivity of ice is 2.2 W/m.K. What is the temperautre of icesheet at its center (i.e., at 1 m from the surface)?
