Fluids are all kinds of substances that can flow and adjust their shape according to the container they occupy, such as liquids, in moving liquids they cannot be separated from the piping system. Where the pipe is a means of fluid distribution tools that are widely applied to households and industries from shelters to places of use that require piping installations with various diameter sizes and each pipe installation has a flow loss. This study uses experimental methods and data collection analysis by measuring headloss and pressure differences between U and digital manometers on ½, ¾, and 1 inch pipes with variations in flow rate of 5, 10, 15 lpm. This shows that the smaller the pipe diameter, the greater the flow loss and pressure difference. This can be seen from the value of the flow loss that occurs in the ½ inch pipe is 6.314x10-2 m while the value of the pressure difference is 321 Pa.
