Abstract
Hydraulic ram pumps offer an energy-efficient solution for water lifting, crucial in rural areas with limited electricity access. Comparative analysis using Response Surface Methodology (RSM) and Taguchi method reveals distinct experimental designs and optimization outcomes. RSM entails 20 experiments, yielding optimal points at Input Height (3 m), Input Length (12 m), and Vacuum Tube Length (120 cm). In contrast, Taguchi employs 9 experiments, with optimal points at Input Height (3 m), Input Length (6 m), and Vacuum Tube Lenght (120 cm). For the equation model, the RSM method shows a complex mathematical equation involving interactions between variables, while the Taguchi method provides a simpler equation. As for the most optimal variable when viewed from the Significant value in both methods in the ANOVA table, it is found that the input height variable is the most significant variable in optimising the response (discharge). A better understanding of these two methods can help the selection of appropriate methods for specific situations, strengthen the understanding of hydram pump performance, and contribute to the development of more efficient and sustainable hydram pump technology.
