Exercise C
67
If there is sufficient laboratory time then the investigations of feed rate and inlet/outlet
flow rates may be repeated at this increased volume. Remember to create a new
results sheet for each investigation.
Results
For easy identification or results, it is suggested that each results sheet is renamed
with a descriptive title (e.g. ‘Flowrate’, ‘Volume’, etc.). The entire workbook should be
saved with a suitable filename for future reference (e.g. PCT40 Exercise C).
Each set of data should be plotted on a graph of fluid level against time.
Make a comparison of each variation in the experimental conditions against the
results for basic manual control during the first part of the exercise.
