A flat plate of 0.6 m height by 0.05 m width has a surface temperature of 270°C and is exposed to an environment with air at Too= 280C and h=35 W/m2.K. In order to increase the heat transfer rate from the surface, fins with constant cross section will be added to the surface. Each fin will be 6 mm thick and 140 mm long, and will be made out of aluminum, kal = 240 W/m-K. The space in between fins is 3 times the fin thickness. For a single fin arrangement (i.e, fin and plane wall), find abcd in pict
