Question

The upper surface of a 1-m × 1-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 local convection heat transfer coefficient along the plate surface is correlated with the correlation h_x = 1.36 x^-0.5, where h_x and x have the units W/m²·K and m, respectively. The maximum use temperature for the ASTM B152 copper plate is 260°C (ASME Code for Process Piping, ASME B31.3-2014, Table A-1M). Evaluate the average convection heat transfer coefficient h for the entire plate. If the rate of convection heat transfer from the plate surface is 700 W, would the use of ASTM B152 plate be in compliance with the ASME Code for Process Piping?
