Question

Need help with problem 5.26, help me understand, please explain in detail and write clearly. thanks in advance.

5.24 Water enters the horizontal, circular cross-sectional, sudden- contraction nozzle sketched in Fig. P5.24 at section (1) with a uniformly distributed velocity of 7.5 m/s and a pressure of 500 kPa. The water exits from the nozzle into the atmosphere at section (2) where the uniformly distributed velocity is 30 m/s. Determine the axial component of the anchoring force required to hold the contraction in place. CI 40 m/s Section (2) D 7.5 cm P2 = PI 500 kPa IVi 7.5 m/s 0 kPa V2= 30 m/s FI Section (1) FIGURE P5.24
