The improper design of water supply system due to the improper consideration to the losses will cause a water shortage at certain area. Hence, it will cause the water supply does not archive the demand in that area. This research is about the determination of the relationship between head loss and the characteristic of piping system. The first objective in this research is to determine the total head loss by using the Darcy-Weisbach equation and HazenWilliams equation. Through this research, it shows that the head loss calculated by DarcyWeisbäch equation have higher accuracy than using the Hazen-Williams equation. The loss due to the each component of the piping system also is ones of the objectives in this research and it were determined and compared with the theoretical methods. From this research, it shows the minor head loss is increases when the flow rate increases for every component in piping system and the least percentage of difference for minor head loss is around 6.45 % for globe valve. The total head losses due to various temperatures also were determined and compared by using Hazen-Williams equation and Darcy-Weisbach equation. The head loss given by-the Darcy-Weisbacli equation is closer-to the experimental-bead loss compared toHazen-Williams equation. The relationship between head loss and flow rate in piping system also were determined in this research. The finding in this research shows that the total head loss is increases when the flow rate also increases. In 'a nutshell, this research is important to provide more information regarding to the head loss for the future researches also can minimize the error during design the water supply system.
