Calculation question (10marks, scan and upload the handwritten workout in the final of this exam): The boundary conditions of a plate are shown in the following Figure. The thermal conductivity, k of the plate is 60 W/m.K. There is no heat generation of the plate. By treating the problem as a 2-dimensional heat transfer with one element (1) and four nodes 1, 2, 3 and 4. Fixed temperature at 100 C predetermined as [K] 100 mm T= 20 C, h=200 W/m.K (1) K=60 W/m.K 3 2 50 mm Insulated T=50 C, h=100 W/m.K The global thermal conductance matrix (thermal stiffness matrix) with the consideration of all boundary conditions, has been 53.33 11.67 -25 -35 1 11.67 53.33 -35 -25 2 -25 -35 56.67 13.33 3 35 -25 13.33 56.67 4 Calculate the global thermal load vector of element (1) with the consideration of all boundary conditions.
