Say we have the series of rectangles as illustrated below (all lines are straight and ignore any wavy lines). They are each marked zones A-D, with D being the atmosphere. The atmosphere, labeled as D, is the surroundings of the rectangles, with a temperature of 350 K. The rectangular surface labeled as A has the temperature of 700 K. Rectangular surface C is| assumed to have insulation, so the there is no heat transfer in the form of radiation occuring. All the surfaces shown are assumed to be a black-body radiator, and the angle between B/C is 90 degrees and perfect. Surfaces A/B are in the same plane. All rectangles are assumed to be steady state condition. Find the following: 1. The View Factor (Fac, Fbc, Fad, Fbd, Fcd) 2. Find the net radiation flux for the rectaunglar surfaces A/B/D. 3. Find the termpatuer at the surface of the rectangular surface C. コM s meters 5 meters

As the temperature differential across a panel increases, A. the rate of heat transfer through the panel will increase. B. the rate of heat transfer through the panel will decrease. C. the rate of heat transfer through the panel will remain unchanged since the temperature difference does not affect the rate of heat transfer.
1.3 A furnace wall is to be constructed of brick having standard dimensions of Two kinds of material are available. One has a maximum usable temperature of 1040°C and a thermal conductivity of 1.7 W/(m K), and the other has a maximum temperature limit of 870°C and a thermal conductivity of 0.85 W/(m K). The bricks have the same cost and are laid in any manner, but we wish to design the most economical wall for a furnace with a temperature of 1040°C on the hot side and 200°C on the cold side. If the maximum amount of heat transfer permissible is 950 , determine the most economical arrangement using the available bricks.

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. What is the total mass of the iceberg? Express answer in kg and in scientific notation with two decimal places. To input: if the answer is 4.78x1025, input 4.78e25.
