Figure 4. The Finding of Inverter Pump Setting and Flowrate Measurement.<br />
4 CONCLUSIONS<br />
This project had successfully evaluate and determine the ram pump<br />
performance. At the laboratory scale, it was confirmed that ram pump had<br />
its potential to provide an alternative means of water supply delivery system<br />
through not as efficient as conventional supply. For the study, we had found the<br />
Ram Pump Delivery Ratio (RPDR).<br />
This study had met performance tested of ram pump. Results show that<br />
ram pump will deliver 10% of the incoming water injected to the ram pump<br />
to the end user. Water will be supplied by a ram pump in the ratio of 1:10. For<br />
example, if 10,000m3 go through the ram pump, only 1,000m3 of water will be<br />
the supply volume. This study also had to meet objectives of identifying optimum<br />
sustained water flow from ram pump through simplified calculation in Ram Pump<br />
Design Calculator (RPDC). The RPDC had been produced based on 1:10 ratio<br />
to determine the ram pump size, quantity and requirement according to water<br />
supply demand. Table 9 shows the RPDC.<br />
From the test carried out, it was found as follows: (a) the ram pump could<br />
perform consistent with the mini dam concept; (b) factors affecting the ram<br />
pump performance are the consistency of water sources to start-up the ram<br />
pump. Although the ram pump does not use electricity, some additional<br />
accessories in controlling ram pump performance are recommended to be<br />
