Benchmark of Current System  Poor tool clearance in the proximity of impeller mounting block  Non-standardized force and torque required for impeller switching  Reassembly of mounting plates without sufficient force results in leakage  System drainage is not sufficient; water remains in the impeller compartment during the switching process  Seals are not fully uniform and have sealant build-up  Motor and impeller drive shafts are not lined up appropriately, a flexible connector compensates for this  Water tank capacity is much larger than used within the pump system  Water tank height relative to pump system is opposite of what is desired  Time required to take the mounting block apart and remove impeller and reverse the process is ~10 minutes, only leaving one full hour in the lab period to actually perform flow measurements and visualizations  Tight dowel rods for mounting of the impeller along with the central screw prevent quicker swapping and will not facilitate any impeller changes if the blades are of a more delicate design Engineering Analysis of Preexisting Platform
