Figure 3. Water Flows and Valves Setting During the Ram Pump Testing.<br />
3.5 Result of River Simulation Testing<br />
As the result of Pre-River Simulation Testing, some flow rate setting on Inverter<br />
Pump were found as stable testing methodologies. In this test, Inverter Pump had<br />
been set to six (6) setting which generate incoming water to ram pump from 34.4<br />
to 40m3/hr(50 Hertz). The summary of testing result is as shown in Table 6.<br />
No.<br />
