The surface of a cylinder, having a diameter of 6 in and a

length of 2 ft, is maintained at 300 F. The cylinder is exposed to the cross

flow of carbon dioxide flowing at a steady state velocity of 150 ft/s, a

temperature of 70 F, and a pressure of 1 atm. Assuming the surface emissivity

is very low, find the rate of heat transfer to the cylinder to make up the heat

loss by convection to the cross flow of air and to maintain its temperature at

the specified value.
