Find the Correction for Curvature & Refraction for a Given Distance

Find the Correction for Curvature

Mathematic Problem

Find the correction for curvature for a distance 900 m and 2.5 km.

Solution

1. When the distance is 900 m 0r 0.9 km

Correction for curvature (in meters) = 0.0785 D2

After Putting the value of D in the above equation [D is in Km]

Correction for curvature (in meters) = 0.0785 × 0.92 = 0.063 m

2. When the distance is 2.5 km

Correction for curvature (in meters) = 0.0785 × 2.52 = 0.49 m

Find the Correction for Refraction

Mathematical Problem

Find the correction for refraction for a distance 700 m and 1.5 km

Solution

1. When the distance is 700 m 0r 0.7 km

Correction for refraction (in meters) = 0.0112 D2 = 0.0112 × 0.7 2 = 0.0055 m.

2. When the distance is 1.5 km

Correction for refraction (in meters) = 0.0112 D2 = 0.0112 × 1.5 2 = 0.0252 m.
