3.6.9 WP Water flows from a pressurized tank, through a 6-in.-diameter pipe, exits from a 2-in-diameter nozzle, and rises 20 ft above the nozzle, as shown in Fig. P3.6.9. Determine the pressure in the tank if the flow is steady, frictionless, and incom- pressible.20 ftAir+2 in.2 ft16 in.FIGURE P3.6.9
