The elevation of thetop of the footing is 102.33’. the elevation of the existing grade is 106.14’. the backsight of thesurveying instrument on a benchmark of 100.00’ is 6.78’. what is the correct reading for the rodat the bottom of the footing?
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.
