Question: A packed tower with the following hydraulic data needs to be evaluated: The diameter of the packed column is 1.25 m and the packing used

A packed tower with the following hydraulic data needs to be evaluated: The diameter of the packed column is 1.25 m and the packing used is 1 inch metal Pall Rings 3.1 Calculate the percentage flooding. (8) 3.2 If the maximum allowed pressure drop for the column was specified at 900 Pa/m, determine whether the specified packing will achieve this. (2) 3.3 If a larger sized metal Pall ring (1.25 inch) is used, determine whether a pressure drop reduction would be realised and determine if percentage flooding is acceptable. (5) 1 cP = 0.001 Ns/m2 1 mm H2O = 9.81 Pa
