6.48 This "double" nozzle discharges water (p = 62.4 lbm/ft³) into the atmosphere at a rate of 16 cfs. If the nozzle is lying in a horizontal plane, what X-component of force acting through the flange bolts is required to hold the nozzle in place? Note: Assume
irrotational flow, and assume the water speed in each jet to be the same. Jet A is 4 in. in diameter, jet B is 4.5 in. in diameter, and the pipe is 1.4 ft in diameter.

6.85 A reducing pipe bend is held in place by a pedestal as shown. There are expansion joints at sections 1 and 2, so no force is transmitted through the pipe past these sections. The pressure at section 1 is 20 psig, and the rate of flow of water (p = 62.4
Ibm/ft³) is 2 cfs. Find the force and moment that must be applied at section 3 to hold the bend stationary. Assume the flow is irrotational, and neglect the influence of gravity.

- Post-tensioned AASHTO Type III girders are to be used to support a deck with unsupported span equal to 90 feet. One level of Grade 270, 10 x 0.6" Ø 7-wire strand are used to tension the girders. The girder is simply supported at both ends. The anchors are located 2" from the neutral axis at the supports while the eccentricity is measured at 14" at the midspan. Use maximum values for ranges (table values). The tendons are encased in flexible metal sheathing. Assume and loadings are placed immediately after stressing. Determine the stresses at the top and bottom of the beam, including the stress at the level of steel after three years.
