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.

Question
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 25
W/m²·K. (same as above). In this task, you are asked to design fins to cool a
surface by attaching 3 cm-long, 0.25 cm-diameter aluminum pin fins (thermal
conductivity, 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 the
finned structure to the air for a 1 m x 1 m section of the plate.
