What will be an ideal response?
The upper surface of a plate is bolted with ASTM B21 naval brass bolts. The bottom surface of the plate is fully insulated. The upper plate surface is exposed to convection at an air temperature of 50°C and a convection heat transfer coefficient of 5 W/m2•K. Also, thermal radiation exchange occurs between the upper plate surface and the surrounding surface temperature of 300°C. The emissivity of the plate surface and the bolts is 0.3. The ASME Code for Process Piping (ASME B31.3-2014) limits the maximum use temperature of B21 bolts to 149°C. Determine whether the ASTM B21 bolts on the plate comply with the ASME code.
