A line of levels 10km long was run over soft ground. Starting from BM1 with the elevation 22.5 meters. The elevation of BM2 was computed to be 17.25m. It was found out however that the level settles 5mm between the instant of every backsight reading, the rod settles 2mm if the backsight and foresight distance have an average of 100m.Find the correct elevation of BM2.
