Pengaruh varisi panjang pipa input dan diameter lubang katup limbah terhadap unjuk kerja pompa hidram (hydraulic ram)
Water is one of the most important basic needs in human life and all living things that exist on this earth. To meet the availability of water is needed tool that can be easier, economical and efficient. Hydraulic ram pump (hydram) is one type of water pumping equipment, it does not use fuel oil or electric power in its use. The purpose of this research is to know the influence of variation of input pipe length and diameter of valve of waste valve to output discharge and efficiency of hydram pump. In this research the height of the sink (H) from the water source to the position of the pump holder is 2 meters while the output height (h) 5 meters. The size of a 1 ½-inch hydramm pump designed by the researcher. Diameter input pipe 1 ½ inch, and output ½ inch, while for air tube diameter 3 inch with height 60 cm. As for the length of the input pipe varies from 2 meters, 4 meters, 6 meters, and 8 meters. In this research also used variation of the diameter of the valve sewage hole, ie from ½ inch, ¾ inch, and 1 inch with a step step valve waste 1.5 centimeters. The results of the research showed the largest output discharge at the length of the input pipe 6 meters and 8 meters with the diameter of the 1-inch waste valve hole, while the output discharge was mined to the length of the 2 meter input pipe with the diameter of the ½ inch waste valve. The best efficiency is 57.3283% on the length of the 8 meter input pipe with the diameter of the 1-inch waste valve hole, while for the worst efficiency of 17.1707% on the length of the 2 meter input pipe with the diameter of the ½ inch waste valve.
