Extracted text: In a portion of the square, 2-D finite difference mesh shown, node 2 is located on an insulated edge. The thickness and thermal conductivity of the region are 1.50 mm and 20 W/m-K, respectively. If there is a point heat source of 1.2 W at node 2, calculate the steady temperature of node 2. 5. T = 40°C 1 T; = 52°C T = 60°C Q,= 1.2 W 4 2 8 = 1.50 mm k = 20 W/m K 3
