CBE 320 November 2, 2009 Transport Phenomena Problem Session X 1. Fiber spinning In the fber-spinning process shown in the fgure below, the cylindrical fber Fows through a nozzle with uni±orm speed V o , and enters into a cooling water bath o± constant, uni±orm temperature T .A t large z (the direction o± Fow), ±ar away ±rom the nozzle, the fber temperature is the same as that o± the bath. Assume that the heat trans±er coe±fcient between the fber and the water bath, h ,thethermal conductivity o± the fber, k , the fber density,

Use the shell energy balance method to derive the dierential equation or the temperature profle in the fber T ( z ) or this situation. b. Indicate the boundary conditions you should use to solve this dierential equation. c. Solve this dierential equation to determine the temperature profle. 2.
