Earth pit calculation formula

WebTo measure the soil resistivity start the Fluke 1625 and read the resistance value in ohms. In this case assume the resistance reading is 100 ohms. So, in this case we know: A = 3 meters, and. R = 100 ohms. Then the soil resistivity would equal: r= 2 x p x A x R. r = 2 x 3.1416 x 3 meters x 100 ohms. WebRound Concrete Earth Pit Chamber. ₹ 450 Get Latest Price. Weight: 25kg.
