50. 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 548 IVb. Heat Transfer: Forced Convection 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.
