Consider 6.17. The stationary plate, ambient air, and surroundings are at T Tsur 20C. If the rotating disk temperature is Ts 80C, what is the total power dissipated from the disks top surface for g 2 mm, 150 rad/s for the case when both the stationary plate and disk are painted with Parsons black paint? Over time, the paint on the rotating disk is worn off by dust in the air, exposing the base metal, which has an emissivity of 0.10. Determine the total power dissipated from the disks worn top surface. 13.9
