Unformatted text preview: system parameters (driving pressure, line length, etc.) The surge pressure also depends on how fast the valve is closed off. Therefore, you should obtain the results by closing the valve aggressively. The bench scale experiment was set up with a water supply pressurized by the shop air. Performing tests to a maximum pressure of 400 kPa gauge would be adequate. In the set up, there are several supply lines with different lengths and diameters. To minimize water waste, water is only turned on when you hold the solenoid valve open (i.e. holding down the red button on the control panel).
