Volume Thermal Expansion α_{V} Formula & Calculator
 

Volume thermal expansion coefficient α_{V} calculator  step by step calculation, formula & solved example problem to find the change in material's Volume dimensions to change in temperature. Volume of an object V in m^{3}, change in Volume ΔV in m^{3} and change in temperature ΔT in kelvin are the key terms of this calculation.
Formula
In heat transfer, the below mathematical formula is used to calculate the coefficient of change in material's volume dimensions to change in temperature.
Solved Example
The below step by step solved example problem may helpful for users to understand how the input values are being used in such heat transfer calculations to calculate the coefficient of change of volume with respect to change in temperature.
Example Problem
Find the thermal coefficient of material whose Volume V is 4 m^{3}, change of volume ΔV is 4.8 m^{3} & change of temperature ΔT is 90 kelvin.
Solution
The given data
Volume V = 4 m^{3}
change of volume ΔV = 4.8 m^{3}
change of temperature ΔT = 90 kelvin
Step by step calculation
Formula to find α_{V} = 1/V (ΔV/ΔT)
substitute the values in the above formula
= [(1/4) x (4.8/90)]
= 0.013
α_{V} = 0.013
