Proper design of new valves requires accurate determination of the water impulse force and moment on the disk for transient flow conditions. The impulse moments were measured using pressure measurement and strain gauge measurements. Correlation was developed relating the impulse moment to the velocity and angle that were used to design a new type of valves.展开更多
