6.52 For this wye fitting, which lies in a horizontal plane, the cross-sectional areas at sections 1, 2, and 3 are 1 ft², 1 ft², and 0.25 ft², respectively. At these same respective sections the pres- sures are 1000 psfg, 900 psfg, and 0 psfg, and the water discharges are 20 cfs to the right, 12 cfs to the right, and exits to atmo- sphere at 8 cfs. What x-component of force would have to be ap- plied to the wye to hold it in place? 20 cfs 2 12 cfs (3) PROBLEM 6.52 30° -x
