Required information
Hot gas flows in parallel over the upper surface of a 2-m-long plate. The velocity of the gas is 13 m/s at a temperature of
250°C. The gas has a thermal conductivity of 0.03779 W/m-K, a kinematic viscosity of 3.455 × 10-5 m²/s, and a Prandtl
number of 0.6974. Two copper-silicon (ASTM B98) bolts are embedded in the plate: the first bolt at 0.5 m from the leading
edge, and the second bolt at 1.5 m from the leading edge. The maximum use temperature for the ASTM B98 copper-
silicon bolt is 149°C (ASME Code for Process Piping, ASME B31.3-2014, Table A-2M). A cooling device removes the heat
from the plate uniformly at 2000 W/m²
