nation 2. Select a single acting Kobe or Delmag diesel hammer using Table 17.4 to drive concrete piles. The piles are 18 inches square, and the weight is approximately 150 lb per cubic foot. The piles will be 75 feet in length. The minimum ratio of the hammer piston weight to the pile weight is to be 1:2 (hammer weight = 0.5 x pile weight). The average penetration per blow for the last 10 blows is 0.5 inches. Based on your hammer selection and the driving information, what will be the safe rated load using the Engineering News equation?
