폴리부틸렌 이중관에서의 워터 햄머 현상에 관한 연구

The Study of Water Hammer in Polybutylene Double Piping System

This study is to investigate the pressure wave characteristics and the maximum pressure rise generated by instantaneous valve closure at the end of the straightening polybutylene double piping system with header. Experiments were conducted under the following conditions: initial pressure $1{\sim}5$ bar, flow velocity $0.5{\sim}3.0$ m/s and water temperature $25^{\circ}C$.
