Question: solve plz A methanol stream from a distillation column is flowing at 8,000lb/hr to be cooled from 130F to 70F using 12,000lbm/hr of cooling water
A methanol stream from a distillation column is flowing at 8,000lb/hr to be cooled from 130F to 70F using 12,000lbm/hr of cooling water at 40F. The convective heat transfer resistance on the methanol side was estimated to be 0.003ft2hF/Btu. Assume that the metallic wall conductive resistance is 0.001ft2hF/Btu and the water side resistance, including the fouling resistance, is 0.002ft2hF/B tu. (a) Solve for q in Btu/hr. (b) Solve for U in Btu/ft2FFhr. (c) Solve for Tlm. (d) What outside area (in ft2 ) is needed for a countercurrent flow heat exchanger? Data: Methanol Cp=0.62Btw/IbmF, Water Cp=1.00Btw/lbmF
