A pump is a device used to move fluid or something in the form of liquid by increasing the pressure so that it can flow from one place to another or from a low surface to a high surface. In everyday life, the need for water is very useful, so it requires a pump to be able to take it or drain it. In this thesis research will be tested by making a pump prototype using a dynamo drive, and changing the shape of the impeller blade and the number of immersions to determine the resulting water pressure and the resulting water discharge. So that it can find out which impellers are effective in producing water and can drain water faster.

Pipes are used as a means of fluid transportation from a reservoir to a destination. In a piping system, flow loss or head loss is always found, both head loss due to pipe size and head loss due to bends, one of which is the knee. The purpose of this study was to determine the effect of knee diameter on flow headloss. The method used is simulation and monogram calculation. Based on the standard ASME B16.9 B16.28 used knees with a diameter of 1, 2, 4 and inch. The experimental results show the same behavior between the simulation and the monogram calculation. The larger the knee diameter, the smaller the head loss. Headloss simulation results for knee diameters 1,2,4 and 6 inches are 0,012 m, 0,0093 m, 0,00063 m and 0,00426 m, respectively. Meanwhile, the headloss calculated by the monogram is 0.006 m, 0.0024 m, 0.0007 m and 0.004 m, respectively. The smallest headloss occurred at 4 inches in diameter indicating that the knee with this diameter is the best knee among the other four knees

“…Sedangkan sudu putar atau rotary blade, mengubah arah dan kecepatan aliran fluida sehingga menghasilkan gaya yang memutar poros. Sudut aliran yang sesuai dapat meminimalkan losses [4] dan mempercepat putaran turbin [5][6][7]. Besar daya yang dapat dihasilkan turbin dari aliran air dapat dihitung dengan rumus berikut : P = ηγQh Dimana : η = efisiensi sistem γ = berat air persatuan volume (N/m 3 ) Q = debit air (m 3 / det) h = ketinggian permukaan (m) P = daya yang diberikan aliran air melalui kincir (watt) Turbin cross flow merupakan jenis turbin impuls yang juga dikenal juga dengan nama turbin Michell -Banki.…”

The potential of hydro energy is very large both for large scale and for small scale. Until now, the need for energy continues to increase, so that energy is a very important element in the development of a country or a region. Cross-flow turbines are one type of turbine that is often used for PLTMH. In this study planning a cross-flow water turbine applied to the height and amount of water per second in the irrigation channel water flow, this water flow will rotate the turbine shaft to produce mechanical energy. With variations in the direction of the turbine flow direction, namely 30o, 35o, and 40o, and the same variation of water discharge 10,5 L / s, 21 L / s and 31,5 L / s to determine the effect on the rotation and the power produced. In this study with 12 turbine blades, 30o blade angle, 40o flow direction angle, and 31.5 L / s water discharge obtained the highest first stage turbine rotation value is 478 rpm. Whereas at the flow direction angle of 30o with the same water discharge which is 31.5 L / s so that the first stage of the turbine is obtained is 296 rpm.
