Indonesia is one of the developing countries with tropical climate in the world. The tropical climate makes regions near equator most likely to have high rate of rainfall that could lead to overflow in places with limited reservoirs and low productivity to some plantation, such as palm trees.. Therefore farmers in Kalimantan create an axial pump from boat impeller so they could relief the flood with the mass flow as high as possible. The reason they buy boat impeller is because this impeller has been a mass product so the cost is relative low and easy to find. Using this type of impeller can be inefficient because this impeller is not designed for pump. Impeller designed for pump may give better performance with efficiency above 60% but the cost is far more expensive than boat impeller in the market. Therefore this final project will discuss boat impeller performance as axial pump by using Computational Fluid Dynamics as software based on numerical method solution to find characteristic curve that describes head, power, and efficiency to fluid mass flow rate on 1700, 2000, 2300 rotational speed per minute of pump. From this information, we could obtain the optimum pump performance using boat impeller with efficiency above 40% at 200-250 kg/s mass flow rate on 1700 rpm and 250-350 kg/s mass flow rate on 2000 and 2300 rpm.
