The local atmospheric pressure in Denver, Colorado (elevation
1610 m), is 83.4 kPa. Air at this pressure and 20°C flows with a
velocity of 8 m/s over a 1.5 m X 6 m flat plate whose
temperature is 140°C . Determine the rate of heat transfer from
the plate if the air flows parallel to the (a) 6-m-long side and (b)
the 1.5-m side.
