An object of irregular shape has a characteristic length of � = 1.00 [�] and is maintained at a uniform surface temperature of �. = 400 [�]. When placed in atmospheric air at a temperature of �- = 300 [�] and moving with a velocity of � = 100 [ 3 . ], the average heat flux from the surface to the air is 13,000[ 2 3&]. If a second object of the same shape, but with a characteristic length of � = 5.00 [�], is maintained at a surface temperature of �. = 400 [�] and is placed in atmospheric air at �- = 300 [�], what will the value of the average convection coefficient be if the air velocity is � = 20 [ 3 . ]?
