Pressure Transient Characteristic in Fluid Condition During Opened and Closed Water Line Based on Experimental Method

Abstract

This paper describes the pressure characteristic of fluid in a water line. There are many factors that influences pressure surge in a pipeline system such as fluid velocity, length, diameter and material of pipe. In this study, experimental data will be analysed for pressure transient study by using different water velocity. The relationship between fluid velocity and pressure will be explained throughout the paper. An experiment has been conducted in two different kinds of water line, which are known as open and close line. To study close water line system certain graph will be analyse to study pressure reaction when changing of the velocity of water. The result of this experiment is the change of fluid velocity may affect the rising or falling of the water pressure. The change of fluid velocity when closing the valve is related to water hammer phenomenon. Water hammer is happening when a fluid in motion is forced to stop or change in flow direction. Experimental data of this study proved that velocity is one of the factor that affects the fluid pressure in the piping system.
