PILOT SCALE TEST EQUIPMENT DESCRIPTION
The eight foot diameter tank and pilot scale pump is
shown in Fig. 1 and Fig. 2. In Fig. 3 a pump of much larger
capacity is shown, where operational details are available
(Leishear, et al. ). CFD models were performed for both
pump systems, and comparisons of experiment to prediction
were performed for each. Velocity measurements were taken
with the same Marsh McBirney, Model 511 equipment, used to
collect velocity data, as shown in Fig. 4. The probes were
installed according to Fig. 5. In the pilot sale tank, probe
locations were as shown in Fig. 6, and probe locations were as
shown in Fig. 7 for the full scale tank.
