Methodological Approach of Performance Evaluation for Using Pump as Micro Hydro-turbine
Abstract
The pumps work differently in terms of performance characteristics when operated in reverse mode to generate mechanical rotational energy driven by the water energy. The performance characteristics related to head, flow rate, specific speed and efficiency have been predicted differently from available conversion methods. Also, the procedure of selecting pump as hydro-turbine varies from different conversion methods. This article presents the methodological approach of evaluating the pump as hydro-turbine related to selection procedures, performance characteristics and challenges.
