How to Calculate and Solve for Total Anomalous Mass | Gravity

Last Updated on April 16, 2024

The image above represents total anomalous mass. To calculate total anomalous mass, one essential parameter is needed and this parameter is Number of Area Segments (n).

The formula for calculating total anomalous mass:

M_E = 23.9 Σ(ΔgδA)

Where:

M_E = Total Anomalous Mass
Δg = Change in Gravity
δA = Area Segment

Let’s solve an example;
Find the total anomalous mass when the number of area of segments is 2 (change of gravity (Δg₁) is 5, area segment (δA₁) is 12, change of gravity (Δg₂) is 8 and area segment (δA₂) is 10).

This implies that;

δA₁ = Area Segment = 12
Δg₁ = Change in Gravity = 5
δA₂ = Area Segment = 10
Δg₂ = Change in Gravity = 8

Δg	δA	ΔgδA
5	12	60
8	10	80

Σ(ΔgδA) = 60 + 80
Σ(ΔgδA) = 140

Therefore,

That is, M_E = 23.9 Σ(ΔgδA)
M_E = 23.9 (140)
M_E = 3346

Therefore, the total anomalous mass is 3346 g.
