Abstract
Smooth pipes are closed and circular conduits through which fluids are transported under pressure. Secondary energy losses in smooth pipes occur due to several factor such as inlet, valves, enlargement, construction, bend, outlet. Therefore, the purpose of this study was to determine and analyze secondary energy losses on smooth pipes by experimental study. Several stages of research have been set up for this study and some tests were carried out at the Hydraulics and Fluid Mechanics Laboratory of the Civil Engineering Study Program, Maranatha Christian University. Secondary energy losses analysis using the Bernaulli Formula compared to Chezy Formula and Darcy-Weisbach Formula were used to obtain results. The experimental results indicated that all Reynolds Number (Re) value in smooth pipe is 6177 which more than 4000 which all flow regimes categorized as turbulent flows. The experimental results show that the secondary loss due to valve was approximately 0; due to the first bend was 6cm; and due to the second bend was 5.15cm. The anaylsis results of secondary energy losses in smooth pipes has shown a preponderance of the interrelated equations by Darcy-Weisbach Equation and Chezy Equation concerning friction factor in smooth pipes. Thickness of boundary layer (k) of smooth pipe is the most determining variable to categorize the pipe roughness as hydraulically smooth pipes. However, the experimental results presented a set of benchmark data for further research in smooth pipes.
