Steady-state temperatures at selected nodal points of the symmetrical section of a flow
channel are known to be 17= 66.67 °C and T8= 50 °C. The wall has a thermal
conductivity of k= 10 W/m.K. The outer surface of the channel experiences
convection with fluid temperature of To,o= 10 °C and convection coefficient of
ho-250 W/m². K. Determine the temperature at node 3.
