Abstract

The rapid development of technology and the industrial world has led to the development of a piping system that can move fluid from low places to high places or vice versa. Communities widely use piping systems, with both companies distributing drinking water, oil, and natural gas. They are available in a variety of sizes and shapes of cross-section, and their efficiency depends on minimizing losses in fluid flow. These losses are classified into major head losses and minor losses due to small equipment and accessories in the pipeline. CUSSONS friction loss in pipe apparatus piping system uses material Polyvinyl Chloride (PVC) in a frame with the dimensions of 4.65 m × 0.924 m. Fitting in the piping system consists of long radius elbow 90 ̊, standard radius elbow 90 ̊, Sudden enlargement, sudden contraction, gradual enlargement, and gradual contraction. Some pressure tap are connected with the mercury manometer with specific gravity (SG) 13.6. Head loss of the piping system were analyzed using Darcy-Weisbach equation. This centrifugal pump is driven by a single stage motor, SHIMGE Electric Motor. The test uses a variation of the discharge. Modifications to Sudden and Gradual Difference in Cross-Sectional Diameter. The experimental result shows that loss coefficient (KL) for the sudden enlargement of the 2 inches pipe is 0.886, sudden contraction of 2 inches pipe is 0.7, 2 inches gradual enlargement (A) is 0.634, 2 inches gradual enlargement (B) is 0.718, 2 inches gradual contraction (A) is 0.427, 2 inches gradual contraction (B) is 0.603, 3 inches sudden enlargement of pipe is 1.161, sudden contraction of 3 inches pipe is 1.034, gradual enlargement of 3 inches (A) is 0.717, gradual enlargement of 3 inches (B) is 0.824, 3 inches gradual contraction (A) is 0.488, 3 inches gradual contraction (B) is 0.394, the standard radius elbow 90° is 0.896, the long radius elbow 90° is 1.557, the ball valve fully open is 1.669, the ball valve half open is 41.836. the friction coefficient (f) at the line I pipe is 0.033.
