Chapter 3 Experimental Work Page 3.24 is allowed to flow through ong>theong> system for sufficient time so as to allow air in ong>theong> system to escape. 3. The DPT is calibrated and slurry relative density tests performed. 4. The data logging programme is loaded and initialised. 5. The desired flow rate for a test is achieved by controlling ong>theong> pump speed. The data logging routine is started and ong>theong> magnetic flow meter and DPT outputs logged for three to five minutes (Sive, 1988). Check for drift. The calibration ong>ofong> ong>theong> magnetic flow meter is performed during a test run using timed weigh test samples at different time intervals. A test is completed by repeating ong>theong> run at different pump speeds and ong>theong> data collected is ong>theong>n processed. When a test is performed on ong>theong> Mini Rig, slurry continuously empties into ong>theong> weigh tank and timed weigh test samples are taken at intervals during ong>theong> test for ong>theong> calibration ong>ofong> ong>theong> magnetic flow meter. After a test set has been completed a slurry relative density test is performed again to ensure that ong>theong> slurry density has remained constant. 3.9 CONCLUSIONS The test apparatus used for ong>theong> experimental investigation has been fully described and ong>theong> calibration and test procedures to enable ong>theong> collection ong>ofong> accurate pipeline data have been presented. The test results ong>ofong> ong>theong> non-Newtonian slurries that were tested using ong>theong> apparatus and testing Jrocedures are presented in Appendix A. The results are reviewed in Chapter 4 and Jiscussion arising from ong>theong> results is presented in Chapter 5.
