The report is to be produced using a word-processor. Diagrams may be hand-drawn and photo-copied onto the relevant page. The report should have a title and identify the author. The report is to be no more than 8 single-side A4-pages (excluding cover, table of content and appendices) with a size 11 font and at least single-spacing. Anything beyond this limit will be ignored.

Find pressure drop
What we have/can find:
a We can measure the height ofthc packed column (L)
o Superficial Velocity Calculation:
u 1 9.

We know the flow rate of the inlet air
The area of the column can be calculated:
A = rrrz
We can measure the diameter of the column F3 i
o Equivalent Diameter can be calculated for the packing: 7 “packing’s to a graduated
