Reverse engineering of impellers to reduce pipe network pressure and enable sustainable power generation using pumps as turbines (PATs)

Results in Engineering
A pump working as a turbine is a hydraulic machine type that can operate as both a pump and a turbine (PAT) by reversing the flow direction. The PAT could be an effective method for meeting global energy demands, particularly in rural and isolated areas.
