Steady-state temperatures at selected nodal points of the symmetrical section of a flow channel are known to be T2 = 144.7°C, T3 = 192.9°C, T5 = 115.6°C, 76 = 110.5°C, T8 = 138.2°C, and T10 = 118.6°C. The wall experiences uniform volumetric heat generation of q =2 x 106 W/m³ and has a thermal conductivity of k = 10 W/m.K. The inner and outer surfaces of the channel experience convection with fluid temperatures of Too,= 50°C and Too,o= 25°C and convection coefficients of h;= 500 W/m²-K and ho= 250 W/m²K.
