Weighted Measurement – Problem 2

Differential leveling is carried out from BM21 to BM22 along the three different routes but with same precision. The route lengths and respective difference in elevation as determined in the field work is indicated below.

Route Length (km.) Difference in elevation (m.)
1 8 16.010
2 9 16.100
3 10 16.160
  1. Determine the correction, in millimeters, to the difference in elevation along route 1.
  2. Determine the correction, in millimeters, to the difference in elevation along route 2.
  3. Determine the correction, in millimeters, to the difference in elevation along route 3.
  4. What is the adjusted difference in elevation between BM21 and BM22, in meters?
