If the feed rate to the tower of Exercise 7.41 is increased by 30% with all other conditions except for tower pressure drop remaining the same, estimate for the top and bottom trays:

(a) Percent of flooding,

(b) Tray pressure drop in psi,

(c) Entrainment rate,

(d) Froth height in the downcomer. Will the new operation be acceptable? If not, should you consider a retrofit with packing? If so, should both sections of the column be packed or could just one section be packed to achieve an acceptable operation?
