A hot plane surface is maintained at 100°C, and it is exposed to air at 25°C.The combined heat transfer coefficient between the surface and the air is 25W/m²·K. (same as above). In this task, you are asked to design fins to cool asurface by attaching 3 cm-long, 0.25 cm-diameter aluminum pin fins (thermalconductivity, k = 237 W/m·K) with a center-to-center distance of 0.6 cm. (Tip:do not correct the length). Determine the rate of heat transfer from thefinned structure to the air for a 1 m x 1 m section of the plate.
Heat is generated uniformly in a 4 cm-diameter, 16-cm long solid bar (k=2.4 W/m-K). The temperaturesat the center and at the surface of the bar are measured to be 210 oC and 45 oC, respectively. Calculatethe rate of heat generation within the bar. Solve the relevant energy balance equation and the boundaryconditions to calculate the rate of heat generation within the bar. (6 pts)
