13-45 A dryer is shaped like a long semi-cylindrical 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 black-
body. Determine the length of the dryer so that the materials
are dried at a rate of 0.1 kg/s.
