TM 10-4320-303-13 Figure 2-11. Pressure-Reducing Valve Assembly Location. a. Mark crest of hill on ground profile graph. b. Draw a vertical line downward from hill crest. c. Determine location of pumping station closest to hill crest (on uphill side). d. Draw a horizontal line outward from pumping station until it intersects the vertical line drawn in step b. above. e. Measure footage of horizontal line and footage of vertical line. f. Using formula provided below, determine total hoseline footage between pumping station and hill crest: Total hoseline footage = where, a = horizontal line footage b = vertical line footage g. Using formula provided below, determine friction loss of total hoseline footage in terms of vertical feet: Total hoseline footage x 0.024 = Vertical feet of friction loss in hoseline (0.024 = friction loss conversion factor) h. Using formula provided below, determine total feet of friction loss: Vertical feet of Feet of elevation Total feet friction loss in between pumping = of friction hoseline + station and hill loss crest i. Using formula provided below, convert total feet of friction loss into psi: Total feet of friction loss = friction loss in psi 2.31 (2.31 = psi conversion factor) 2-35
