In cryogenic equipment, cold air flows in parallel
over the surface of a 2-m x 2-m ASTM A240 410S
stainless steel plate. The air velocity is 5 m/s at a temperature of
-70°C. The minimum temperature suitable for the ASTM
A240 410S plate is -30°C (ASME Code for Process Piping,
ASME B31.3-2014, Table A-1M). The plate is heated to keep
its surface temperature from going below -30°C. Determine
the average heat transfer rate required to keep the plate surface
from getting below the minimum suitable temperature.
