Abstract
This study aims to investigate the performance of the advance siphon pump, which is an indigenous knowledge of free energy pump. It was introduced to investigate the potential of conveying water by using the energy equation of fluid mechanics to explain the mechanism of the prototype. The prototype design followed the information by interviewing the expert of Nernporkin learning center in Kanchanaburi province. The study was divided into 3 procedures; 1) investigating the possibility of prototype for pulling water from reservoir to supply the difference levels area, 2) investigating the effect of the difference of the elevation (ΔH) to the discharge rate from outlet, and 3) investigating the effect of outlet pipe length to the discharge rate. The results conclude that the advance siphon can deliver water only when the higher level of reservoir supplies the lower area (ΔH>0), while the minimum of ΔH for water transportation is 0.05 meter. The experimental results confirm that the important parameters affect directly the discharge rates, which are the outlet pipe diameter, the length of the outlet pipe and ΔH. The discharge rate will increase when increasing the ΔH, the outlet pipe diameter and shorten the length of the outlet pipe.
