Question
13-47 A dryer is shaped like a long semicylindrical duct of diameter 2 m. The base of the dryer is occupied with water-soaked materials that are to be dried. The dome of the dryer has a constant temperature of 500°C, while the materials at the base are at 40°C. Both surfaces can be approximated as blackbodies. Determine the length of the dryer so that the materials are dried at a rate of 0.1 kg/s. FIGURE P13–47 Tz = 500°C ----- -D= 2.0 m - T = 40°C
