Hot water vapor flows in parallel over the upper surface of a 1-m-long plate. The velocity of the water vapor is 8 m/s at a temperature of 450°C. A copper-silicon (ASTM B98) bolt is embedded in the plate at mid length. 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). To devise a cooling mechanism to keep the bolt from getting above the maximum use temperature, it becomes necessary to determine the local heat flux at the location where the bolt is embedded. If the plate surface is kept at the maximum use temperature of the bolt, what is the local heat flux from the hot water vapor at the location of the bolt?
