The experimental set up can be seen in figure 1 below. (Can you explain this set up a bit in words (2-3 sentences?)

This experiment consisted of measuring the upflow velocity with different flow rates and different quantities of lime, while always maintaining a suspended column of lime. This was an initial experiment and hence most of the quantities were taken through approximation. The details of the exact quantities of lime and flow rates as well as the results obtained can be found on ANC-Initial Experiment Spreadsheet.
(Can you summarize these results if important in a table or figure?)
The optimum flow rate which could keep the lime suspended without excessive lime coming out (as observed visually) was found to be about 85ml/min. (What is this in terms of an upflow velocity?)
The figure below shows the apparatus used for the first trial, it consists of a glass column connected with a water source regulated by a peristaltic pump. The lime was added manually from the top.
(This paragraph seems to be a little out of place after the results. It seems to belong with the procedure)
