    The present paper deals with convective heat transfer from a horizontal cylinder rotating in quiescent air, experimentally. The average convective heat transfer coefficients have been measured by using radiation pyrometer, which offers a new method. According to the experimental results, a correlation in terms of the average Nusselt number and rotating Reynolds number has been established. The equation, Nū = 0.318 Re(r)0.571, has been found valid for a range of the rotating Reynolds number from 2000 to 40000. The average Nusselt number increased with an increase in the rotating speed. Comparison of the results, with the previous studies, have been showed a good agreement with each other.
