The use of pumps operating as a turbines (PATs) is an alternative cheap solution for the conversion of dissipations along the distribution networks, but a little information about their performance is available.The turbomachinery affinity law can be applied for the evaluation of the performances curves, but can produce relevant errors that can be reduced with a modification of the affinity law. This...
A pump used as turbine (PAT) for the transformation of hydraulic energy in electricity is the new trend in the management of water distribution networks. So far few application of such devices are known for the lack of adequate studies on the PAT project and on the interactions between PAT and the water system. Overall efficiency, flexibility under flow rate and pressure variations, response to unsteady...
