Question

Consider steady, two-dimensional heat transfer in a domain showed below. There is no heat generation, the thermal conductivity k is uniform and the spacing between all the nodes are equal (?x = ?y). Surface boundary conditions are: • convection through nodes 6-7-8-5 • insulated through nodes 1-3-6 • constant heat flux through nodes 1-2-5 Using a finite difference approach and the relevant values below and calculate the temperature in K at the node 7. Mark the nearest answer. T? = 300 K h = 2 W/m"K ?x = ?y = 1 m k = 1 W/mK T3 = 460 K T4 = 420 K T5 = 400 K T6 = 400 K T8 = 320 K
