Download Solution PDFConcept:
In leveling, the height difference between two points is calculated by subtracting the staff reading at the higher point from the staff reading at the lower point. This gives the elevation difference between the two points.
Given Data:
- Staff reading on benchmark at Point B = 2.45 m
- Staff reading at Point A = 1.23 m
Height Difference:
The height difference between Point A and Point B is given by:
\( \text{Height Difference} = \text{Staff Reading at Point B} - \text{Staff Reading at Point A} \)
\( \text{Height Difference} = 2.45 \, \text{m} - 1.23 \, \text{m} = 1.22 \, \text{m} \)
The height difference between Point A and Point B is 1.22 m.
