A 25-mm-diameter hot surface at
is cooled by an air jet exiting a 5-mm-diameter round nozzle with
a velocity of 35 m/s and temperature of 25. The
nozzle exit is 25 mm from the hot surface. Determine the percentage
change in average heat transfer coefficient at the hot surface if
the air is replaced with carbon dioxide or helium. Use material
properties from reputable tables.
