Combined Error Due to Curvature and Refraction Solution

STEP 0: Pre-Calculation Summary
Formula Used
Combined Error = 0.0673*Distance between Two Points^2
c_r = 0.0673*D^2
This formula uses 2 Variables
Variables Used
Combined Error - (Measured in Meter) - Combined error is the error obtained when both curvature and refraction effects are considered during surveying.
Distance between Two Points - (Measured in Meter) - Distance between Two Points is defined as the length of space between two points. For finding the distance when curvature effects are considered, the value must be considered in kilometres.
STEP 1: Convert Input(s) to Base Unit
Distance between Two Points: 35.5 Meter --> 35.5 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
c_r = 0.0673*D^2 --> 0.0673*35.5^2
Evaluating ... ...
c_r = 84.814825
STEP 3: Convert Result to Output's Unit
84.814825 Meter --> No Conversion Required
FINAL ANSWER
84.814825 84.81482 Meter <-- Combined Error

What is the Curvature and Refraction effect on Surveying?

Curvature and refraction effects should be accounted for in precise levelling work and also if the sights are too long. The effect of curvature is to cause the objects sighted, to appear lower then they really are. The effect of refraction is to make the objects appear higher than they really are.
