Chapter 6, Problem 39P
Water flows steadily up the vertical 1 -in.-diameter pipe and out the nozzle, which is 0.5 in. in diameter, discharging to atmospheric pressure. The stream velocity at the nozzle exit must be 30 ft/s. Calculate the minimum gage pressure required at section①. If the device were inverted, what would be the required minimum pressure at section ① to maintain the nozzle exit velocity at 30 ft/s?

A large lawn sprinkler with two identical arms is used to generate electric power by attaching a generator to its rotating head. Water enters the sprinkler from the base along the axis of rotation at a rate of 5 gal/s and leaves the nozzles in the tangential direction. The sprinkler rotates at a rate of 180 rpm in a horizontal plane. The diameter of each jet is 0.5 in, and the normal distance between the axis of rotation and the center of each nozzle is 2 ft. If the rotating head is somehow stuck, determine the moment acting on the head.
Two circular water jets (d = 0.5 in.) issue steadily from this unusual nozzle. If Vj = 80.2 ft/s, what force is required at the flange to hold the nozzle in place in the x-direction. The pressure in the 4 in. pipe (D = 3.5 in) is 50 psig.
The open stream of water seen in the following picture emerges from a nozzle into the atmosphere at sea level, where it then collides with a stagnation tube. If we exclude losses and assume that the pressure at the centerline of section 1 is 110 kPa, we can estimate that the
(a) the mass flow measured in kilograms per second (kg/s), and (b) the height, measured in meters, of the fluid in the stagnation tube.
