Permissible Closing Error for Ordinary Levelling Solution

STEP 0: Pre-Calculation Summary

Formula Used

Closing Error = 24*sqrt(Distance between Two Points)
e = 24*sqrt(D)
This formula uses 1 Functions, 2 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Closing Error - (Measured in Meter) - Closing Error is the error formed during traverse 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

e = 24*sqrt(D) --> 24*sqrt(35.5)

Evaluating ... ...

e = 142.996503453756

Distance between Two points under Curvature and Refraction

LaTeX Go Distance between Two Points = (2*Earth Radius in km*Error due to Curvature+(Error due to Curvature^2))^(1/2)

Distance for small errors under Curvature and Refraction

LaTeX Go Distance between Two Points = sqrt(2*Earth Radius in km*Error due to Curvature)

Error Due to Curvature Effect

LaTeX Go Error due to Curvature = Distance between Two Points^2/(2*Earth Radius in km)

Combined Error Due to Curvature and Refraction

LaTeX Go Combined Error = 0.0673*Distance between Two Points^2
