Analisa Sistem Pemipaan Menggunakan Metode Manual Kalkulasi dan Simulasi Pipeflow pada PUD. Rumah Potong Hewan Kota Medan

Abstract

Pressure losses in the piping system cause additional power to the pump which also causes additional operational costs. The main cause of pressure losses in the piping system is the unevenness of the inside area of the pipes and accessories. This research analyzes the piping system in PUD. Medan Slaughterhouse, starting from the loss of compressive energy, capacity, flow speed, efficiency, and power of the piping system and recommending a better piping system than the existing one. Data on the piping system at PUD. Medan Slaughterhouse was analyzed using fluid mechanics equations such as the Darcy-Weisbach equation and then compared with the results of pipe flow simulation calculations. This experiment provides the following information: Discharge 1.4 L/s, Cross-sectional area of Galvanized pipe/Pipe 1 0.0064 m2, Cross-sectional area of PVC pipe/Pipe 2 0.0042 m2, Fluid velocity of Pipe 1 0.0255 m/s, Fluid Speed of Pipe 2 0.333 m/s, Relative Roughness Value of Galvanized Pipe 0.0016, Relative Roughness Value of PVC Pipe 0.000006, Reynold Number of pipe 1 19985, Reynold Number of pipe 2 24075.8, Total Head of Galvanized and PVC Systems 0.16602 m, Galvanized System Total Head 0.17802 m, PVC System Total Head 0.15902 m, Galvanized and PVC System Hydrolysis Power 0.7832 Kw, Galvanized System Hydrolysis Power 0.7834 Kw, PVC System Hydrolysis Power 0.7831 Kw, Galvanized System Pump Efficiency and PVC 14.24%, Galvanized System Pump Efficiency 14.243%, PVC System Pump Efficiency 14.238%, Galvanized and PVC System Pump Power 0.055 Kw, Galvanized System Pump Power 0.055 Kw, PVC System Pump Power 0.055 Kw and the calculation results using pipeflow simulation are relatively the same.
