Gold mining Pipe with slurry was modified to observe its effect in pressure-discharge pipe. The fluid was transport using centrifugal pump, while the model simulated using solid work 2018 edition. Three models used in this case were: 28-inch pipe without reducer-pipe; 30-inch pipe without reducer pipe, and 28-inch pipe with reducer-pipe. Each model will produce the discharge pressure, slurry velocity, and the friction. The result shows that the 30-inch pipe without reducer will increase the pressure on the discharge pipe. However, the pressure is not as homogenous as 28 inch-pipe without reducers. 10 % of slurry produced less pressure because the friction occurred in the wall caused by the diameter difference. Meanwhile, the models in 28-inch pipe with reducer-pipe clearly show significant improvement of discharge-pipe pressure. However, the pressure is variety from the centre to the edge of the pipe, with the highest pressure located in the centre of pipe.
