Question

Water enters the horizontal, circular cross-sectional, sudden contraction nozzle sketched in Fig. P5.42 at section (1) with a uniformly distributed velocity of 20 ft/s and a pressure of 67 psi. The water exits from the nozzle into the atmosphere at section (2) where the uniformly distributed velocity is 80 ft/s. Determine the axial component of the anchoring force required to hold the contraction in place (positive if directed to the right, negative otherwise).
