The surface of a 50-mm-diameter, thin-walled tube is maintained at 100 c. in one case air is in cross flow over the tube with a temperature of 25 c and a velocity of 30 m/s. in another case air is in fully developed flow through the tube with a temperature of 25 c and a mean velocity of 30 m/s. compare the heat flux from the tube to the air for the two cases.
