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 of 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

Mathematical Problem

Find the correction for refraction for a distance of 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.
