1 m Valve 3.83. Figure 3.64: Water fountain system Consider the illustration in Figure 3.65 where water is discharged vertically from a nozzle and rises to a height of 8 m. The exit diameter of the nozzle is 25 mm, and the diameter of the conduit leading to the nozzle is 100 mm. If a pressure gauge is located 1 m below the nozzle exit, what pressure is the gauge expected to show? 25-mm T 8 m Pressure gauge Flow 1 m 100 mm Figure 3.65: Vertical discharge from a nozzle
