In cryogenic equipment, cold gas flows in parallel over the surface of a 1-m × 1-m astm a240 410s stainless steel plate. the average convection heat transfer coefficient for the plate surface is correlated with the gas velocity as h = 6.5v0.8 , where h and v have the units w/m2⋅k and m/s, respectively. the temperature of the cold gas is −50°c. the minimum temperature suitable for the astm a240 410s plate is −30°c. to keep the plate’s temperature from going below −30°c, the plate is heated at a rate of 990 w. determine the maximum velocity that the gas can achieve without cooling the plate below the suitable temperature set by the asme code for process piping. the maximum velocity that the gas can achieve without cooling the plate below the suitable temperature is m/s.
