Abstract—This paper aims at investigating the impact of the utilized turbine design on the harvested energy from in-pipe systems. Four turbine designs are involved in this study which includes the spherical turbine and the Helical (Egg Beater) with three blades, four blades, and five blades. The proposed turbines are designed and they have been implemented in a prototype to determine the performance of each design. The study presents design procedures and the design requirements of each employed turbine before the implementation phase. The next step is to collect the produced torque, rotational speed, pressure drop, and output power for each turbine experimentally. The results have been analyzed and compared to show the design impact on these parameters. Finally, a case study is carried out on the major water distribution network in Amman the capital of Jordan to determine the possible locations, which are benefited from the implementation of the in-pipe system with the examined turbines.
