A hole of diameter D = 0.25 m is drilled through the center of a solid block of square cross section with w = 1m on a side. The hole is drilled along the length, 1 = 2 m, of the block, which has a thermal conductivity of k = 150 W/m · K. The outer surfaces are exposed to ambient air, with T8,2 = 25°C and h z = 4 W/m2 · K. while hot oil flowing through the hole is characterized by Tx.1 = 300°C and h1 = 50 W/m2 · K. Determine the corresponding heat rate and surface temperatures.
