Chapter 4, Problem 85P
A nozzle for a spray system is designed to produce a flat radial sheet of water. The sheet leaves the nozzle at V2 = 10 m/s, covers 180° of arc, and has thickness t = 1.5 mm. The nozzle discharge radius is R = 50 mm. The water supply pipe is 35 mm in diameter and the inlet pressure is p1 = 150 kPa absolute. Evaluate the axial force exerted by the spray nozzle on the coupling.

The water enters the sprinkler nozzles with a flow rate of 50 liters / hour in the vertical axis direction and leaves the sprinkler nozzles as 25mm diameter jets and making θ angle with the tangential direction as shown in the figure. The length of the sprinkler arms is 0.45 m. Without considering friction effects; For θ = 75 °, set the rotational speed in rpm.
A nozzle that discharges a 60-mm-diameter water jet into the air is on the right end of a horizontal 120-mm- diameter pipe. In the line, the water has a velocity of 4 m/s and a gage pressure of 400 kPa. Find the magnitude and direction of the resultant axial force the water exerts on the nozzle and the head loss in the nozzle.
The liquid being lifted by the pump below is gasoline with specific weight γgasoline = 47 lb/ft3 and a vapor pressure of 9 psi (absolute). The local atmospheric pressure is patm = 12.5 psi (absolute). The friction head loss through the pipe from its entrance to the pump entrance at B is hf = V 2 /(2g) empirically, where the velocity in the pipe is V = 7 ft/s. What is the maximum allowed value of z without cavitation occurring at the pump entrance at B?
