The surface of a cylinder, having a diameter of 25 cm, is
maintained at 140 C. Air flows over the cylinder at a steady state velocity of
50 m/s, a temperature of 35 C, 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 loss by convection to the cross flow of air and maintain its temperature
at the specified value.
