Volume Thermal Expansion αV Formula & Calculator

Volume Thermal Expansion Coefficient Calculation

V - Volumn of the object (m3)
ΔT - Change in Temperature (K)
ΔV - Changed in volumn (m3)

Volume thermal expansion coefficient αV 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 m3, change in Volume ΔV in m3 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 m3, change of volume ΔV is 4.8 m3 & change of temperature ΔT is 90 kelvin.
Solution
The given data
Volume V = 4 m3
change of volume ΔV = 4.8 m3
change of temperature ΔT = 90 kelvin

Step by step calculation
Formula to find αV = 1/V (ΔV/ΔT)
substitute the values in the above formula
= [(1/4) x (4.8/90)]
= 0.013
αV = 0.013
