A plane wall (k = 1 W/mK) has a thickness of 0.3 m, height of 2 m, and width of 1 m. It undergoes uniform volumetric heat generation of 1,000 W/m3. The left side of the wall is insulated and the right side is cooled via convection with a heat transfer coefficient of 5 W/m2K and an air temperature of 25Â°C. Fins (k = 1 W/mK) are attached to the right hand side of the wall (fins do not generate heat). The fins are rectangular and span the width of the wall with a thickness of 10 mm and a length of 75 mm. The spacing between fins along the heigth of the wall is 20 mm.

find the temperature of the wall in contact with the air (the base of the fins).
