A row of tubes, equally spaced at a distance that is twice the diameter of the tubes, is positioned between two large parallel plates. The surface temperature of the tubes is constant at 10°C and the top and bottom plates are at constant temperatures of 100°C and 350°C, respectively. If the surfaces behave as blackbody, determine the net radiation heat flux leaving the bottom plate.
