Problem: Calculation of the amount of concrete required to block a 90' bend in an 8" C.I. water main; the normal operating pressure In the pipe will be 65 psi and the soil ondition in the area indicates sand and gravel. 2. Solution - Maximum testing pressure (See Table 1) = 300 pp i = 0.75 TL p Outside diameter f 8 pipe - 9.05 in. = 9.05/12 Go to Table 1: The testing pressure of 300 psi, we see that the thrust on a 90' bed Is 21,360 pounds. - Go to Table 2: Table 2 s the safe be aring load for Sire 9 ntl and gravel: 3,OD0 be ft - Go to Fipgune 1: fgure 1 indicates the position f the can here for blocking the 90• bend. - Go to the speclflcatlons of the pro0at and find dspth of trench (hj = 4 feet - Width or trench (y✓1 - 3 feet With the above assembled informatio n, we proceed to the final calculations: - Area of Concrete (A) Thrust = 21,360 = 712 sq fit.
