The upper surface of a 1-m x l-m ASTM B152 copper plate is being cooled by air at 20°C. The air is flowing parallel over the plate surface at a velocity of 0.5 m/s. The maximum use temperature for the ASTM B152 copper plate is 260°C (ASME Code for Process Piping. ASME B31.3-2014, Table A IM). Determine the average convection heat transfer rate from the plate surface that is required to keep the plate surface temperature from going higher than the maximum use temperature
