Flat-plate solar collectors are often tilted up toward the sun in order to intercept a greater amount of direct solar radiation, as shown in Figure Q2. The tilt angle from the horizontal also affects the rate of heat loss from the collector. Consider a 2 m (height) and 3 m (width) solar collector that is tilted at an angle 0 from the horizontal. The back side of the absorber is insulated. The absorber plate and the glass cover, which are spaced 2.0 cm from each other, are maintained at temperatures of 75°C and 35°C, respectively. Analyse the solar collector for different angle, 0 = 0°, 20°, and 90° to select which 0 gives the lowest rate of heat loss from the absorber plate by natural convection.

You can neglect radiation at the bottom of the plate; the bottom side of the plate has water flowing underneath it. Often, when dealing with liquids (rather than gases), one can neglect radiation because heat transfer due to convection is so much larger (liquids tend to have higher convection coefficient values than gases).
An enclosure has an inside area of 50 m², and its inside surface is black and is maintained at a constant temperature. A small opening in the enclosure has an area of 0.03 m². The radiant power emitted from this opening is 52 W. What is the temperature of the interior enclosure wall, in K? If the interior surface is maintained at this temperature, but is now polished so that its emissivity is 0.15, what will be the value of the radiant power emitted from the opening, in W?

Consider a silicon wafer positioned in a furnace that is zone-heated on the top section and cooled on the lower section. The wafer is placed such that the top and bottom surfaces of the wafer exchange radiation with the hot and cold zones respectively of the furnace. The zone temperatures are Tsur,h = 1050 K and Tsur.e = 330 K. The emissivity and thickness of the wafer are e = 0.65 and d = 0.78 mm, respectively.

Determine the heat loss by radiation from an oven wall to the wall of a room to which the oven wall is directly facing. Assume that no heat flows through the adjacent walls, which are coated with a reradiating material. The oven wall is square, 4 ft on one side, and is 2 ft from the room wall and parallel to it. The oven wall is steel sheet and is at 400°F, and the wall is at 80°F and is of asbestos board.
A composite wall is comprised of two large plates separated by sheets of refractory insulation. In the installation process, the sheets of thickness L = 50 mm and thermal conductivity k = 0.05 W/mK are separated at 1-m intervals by gaps of width w = 10 mm. The hot and cold plates have temperatures and emissivities of T1 = 400 deg C, emissivity1 = 0.85 and T2 = 35 deg C, emissivity2 = 0.5, respectively.
