A nonmetal plate (k = 0.05 W/m•K) and an ASME SA-240 stainless steel plate (k = 15 W/m•K) are bolted together by ASTM B21 naval brass bolts. Both plates have a thickness of 38 mm, and the brass bolts are bolted through both plates. The bottom steel plate surface (surface 1) is subjected to a uniform heat flux of 200 W/m2. The top nonmetal plate surface (surface 2) is exposed to convection at an air temperature of 20°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 30°C. The emissivity of the plate surface and the bolts is 0.3. The ASME Boiler and Pressure Vessel Code (ASME BPVC.IV-2015, HF-300) limits the maximum use temperature to 260°C for the SA-240 steel
plate. The ASME Code for Process Piping (ASME B31.3-2014) limits the maximum use temperature of B21 bolts to 149°C. Determine whether both ASME codes are being complied with under these conditions
