Abstract

Pipe as a tool to distribute fluid from the reservoir to the place of use. To carry out the installation of pipes required a piping system. Piping systems are widely used in industry, factories or transportation to distribute fluids. In fluid distribution there will be a loss of fluid energy due to resistance in the pipe. There are 2 types of flow losses, namely major losses and minor flow losses. This energy loss cannot be observed directly. This study aims to create and test a flow loss test apparatus or fluid friction apparatus to analyze flow losses and also things that affect fluid flow losses. used. The pipes used in this research are ¾ inch stainless steel pipe, 1/2 inch aluminum pipe and also ½ inch and ¾ inch PVC pipes. The fluid is flowed using a pump. The test is done by comparing the flow loss theoretically and by measurement. The results of the test showed that the largest loss value was on ½ inch aluminum pipe at 1200 L/h discharge, which was 0.517835671 m, while the lowest flow loss was found in ¾ inch stainless steel pipe with 800 L/h discharge, which was 0.040881764 m and the highest minor loss was obtained. on the gate valve with a discharge of 1200 L/h and a full opening of 0.735872 m. From the test, it is concluded that the major flow loss is influenced by the coefficient of friction of the pipe, the dimensions of the pipe and the flow velocity
