For the fin equation described in Problem 6.25, if the units of T, h, P, A, and x are expressed in degree Rankine (R), Btu/hr ft2R, ft, ft2, and ft, respectively, what is the appropriate unit for thermal conductivity k if the fin equation is to be homogeneous in units? Show all steps of your work.

Why is it so difficult to process MSW?

Two materials, A and B, are to be separated using two unit operations, 1 and 2. The feed has 10 tons/h A and 4 tons/h B. The split (fraction of material rejected by each operation) is given in Table P5-14. a. Which sequence of operations, (l?2) or (2?1), will yield the greatest recovery of material A? b. What will be the purity of material A using that sequence? c. What will be the efficiency of separation for the entire process train with regard to material A using the Worrell-Stesed equation?
