Flat-plate solar collectors are often tilted up towardthe sun in order to intercept a greater amount of direct solarradiation. The tilt angle from the horizontal also affects therate of heat loss from the collector. Consider a 1.5-m-highand 3-m-wide solar collector that is tilted at an angle u fromthe horizontal. The back side of the absorber is heavily insulated.The absorber plate and the glass cover, which arespaced 2.5 cm from each other, are maintained at temperaturesof 80°C and 40°C, respectively.

Four power transistors, each dissipating 12 W, are mounted on a thin vertical aluminum plate 22 cm * 22 cm in size. The heat generated by the transistors is to be dissipated by both surfaces of the plate to the surrounding air at 25°C, which is blown over the plate by a fan. The entire plate can be assumed to be nearly isothermal, and the exposed surface area of the transistor can be taken to be equal to its base area. If the average convection heat transfer coefficient is 25 W/m2·K, determine the temperature of the aluminum plate. Disregard any radiation effects.
