Experimental Performance Analysis of Axial Flow Pumps at Various Pressure Heads

Nowadays pumps are being widely used in commercial, industrial, and power plants to move fluids; consequently, the energy consumption of pumps has become a subject of interest. The purpose of this paper is to investigate the efficiency of axial flow pumps at various pressure heads: the experiment was conducted at 10 kPa, 15 kPa and 20 kPa. The results show an energy loss of 63 % in this design. Although there was more work input, the pump produced less output and underperformed, as its efficiency was reported to be 37.07%. The flowing fluid in the reservoir and the return line loses energy, which has a significant influence on total energy efficiency and this energy are hydraulic loss.
