Table 1
Comparison of the constraints in the new design approach.
| Constraints | Items | Centrifugal Pump | Mixed-flow Pump |
| Constraint I | of the shroud | 0.4% | 0.16% | of the hub | 1.5% | 1.6% | Design time | 1481 s with 24 control points | 0.304 s |
| Constraint II | of the shroud | 0.81% | 0.21% | of the hub | 2.6% | 1.81% | Design time | 1139 s with 22 control points | 0.202 s |
