Problem 6. To determine the variation of temperature with the x and y position, T(x,y), we should derive energy balance equations for all individual nodes. For this, let's write and simplify equation for node 2 ONLY. You should consider both convection and radiation heat transfer modes where T = 27°C and Tsur = 327°C. You can assume temperatures for node Ti are known. Heat transfer coefficients h and hr for convection and radiation are known, respectively. &= 0.8, Ax = 0.1 m, and Ay = 0.2 m.
