Abstract :
The need for electricity today is generally still
dependent on coal. However, the fact on the ground is
that the amount of coal energy supply for power plants is
in short supply. There must be steps to increase the
supply of power plants that use New and Renewable
Energy sources. Indonesia has the potential to build
power plants that use New and Renewable Energy
sources, namely water energy. In the field, water does
not always have a strong enough discharge to drive a
turbine. Therefore, this research will discuss the effect of
variations in water discharge using a pump so that it can
regulate the flow rate to be used to see the effect of
motor rotation, pressure drop, and power generated.
This research will be conducted at full valve opening, 3/4
intake valve opening, and 1/2 intake valve opening with
variations in rotation from 700 rpm to 1000 rpm. From
the research results, it is found that the higher the pump
rotation, the higher the discharge produced. The valve
opening affects the pressure drop value. Because the
pressure drop has a relationship with cavitation, namely
the formation of vapor in the fluid flow due to a decrease
in pressure. Discharge has a directly proportional
relationship with mechanical power. This can be said
because motor rotation is also directly proportional to
the resulting discharge.
Keywords :
Suction, flowrate, pressure drop.
