How to Calculate and Solve for Linear Expansivity | Thermal Properties
Last Updated on July 24, 2022
The linear expansivity is illustrated by the image below.
To compute for linear expansivity, three essential parameters are needed and these parameters are Original Length (l1), Final Length (l2) and Temperature Rise in Celsius (θ).
The formula for calculating linear expansivity:
α = (l₂ – l₁)/l₁θ
Where;
α = Linear Expansivity
l₂ = Final Length
l₁ = Original Length
θ = Temperature rise (°C)
Given an example;
Find the linear expansivity when the original length is 8, the final length is 10 and the temperature rise is 14.
This implies that;
l₂ = Final Length = 8
l₁ = Original Length = 10
θ = Temperature rise (°C) = 14
α = (l₂ – l₁)/l₁θ
α = (10 – 8) / (8 x 14°C)
α = (2) / (112)
α = 0.0178
Therefore, the linear expansivity is 0.0178 1/K.
