Abstract

Application of the principles of fluid mechanics can be found in the fields of industry, transportation and households. The series of PVC pipes that are used to distribute water at home, of course, has losses caused by its components, one of which is the change in the cross-section of the pipe. One of the energy losses in the change in pipe section is the pressure drop. The pressure drop can be influenced by the fluid flow discharge and the magnitude of the change in the pipe, dibit has fluid flow which causes pressure on the pipe wall. The research in this thesis was carried out in the Mechanical Engineering Laboratory of the Hasyim Asy'ari University. This research is quantitative in nature which will discuss the pressure drop in the sudden change in cross-section which has a diameter of 1 inch to ¾ inch and 1 inch to 1 ¼ inch with variations in valve openings of 100%, 75% and 50%. 1 inch to ¾ inch at each valve opening is 100% 0.1 bar, 75% 0.09 bar and 50% 0.05 bar, while the pressure drop of 1 inch cross section change at each valve opening is 100% equal to 0.03 bar, 75% at 0.03 bar and 50% at 0.06 bar.
