Experimental Investigation of Centrifugal Pump Working as Turbine for Small Hydropower Systems

Himanshu Nautiyal, Varun Varun, Anoop Kumar, Sanjay Yadav Sanjay Yadav


An experimental investigation of centrifugal pump has been carried out to study its characteristics in pump and turbine mode operation. By using the experimental results of tested pump and pumps of some previous researchers, new correlations have been developed by using its best efficiency and specific speed in pump mode. Values obtained from the derived correlations show good match with experimental results. These correlations would be very helpful for the performance prediction of pump working as turbine. Key words: PAT; Centrifugal pump; Specific speed; Best efficiency point


PAT; Centrifugal pump; Specific speed; Best efficiency point
