Water ( = 62.4 lbf/ft 3 ) flows through a horizontal constant diameter pipe with a cross-sectional

Water (γ = 62.4 lbf/ft ³) flows through a horizontal constant diameter pipe with a cross-sectional area of 9 in.2. The velocity in the pipe is 15 ft/s, and the water discharges to the atmosphere. The head loss between the pipe joint and the end of the pipe is 3 ft. Find the force on the joint to hold the pipe. The pipe is mounted on frictionless rollers. Assume α = 1.0 at all locations.
