What is the meaning of inverse design approach for designing your wastewater pump?

The meridional geometry, flow rate, RPM, thickness, and blade loading are the inputs that are used by the inverse design method to give us the final blade design.

Apart from the basic parameters, these blade loading inputs are really flow related. So, once you have a good understanding of your specific pump issue, whether it is profile loss or flow separation or cavitation that you are dealing with, it is possible to come up with guidelines on the optimum blade loading to tackle each of these issues. Furthermore, this works for you regardless of your pump size or speed.

This makes the entire process very intuitive and removes any empiricism that is commonly seen in conventional design methods.
