Area of an object A in m^{2}, change in area ΔA in m^{2} and change in temperature ΔT in kelvin are the key terms of this calculation.
In heat transfer, the below mathematical formula is used to calculate the coefficient of change in material's area dimensions to change in temperature.
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 area with respect to change in temperature.
Example Problem
Find the thermal coefficient of material whose area A is 2 m^{2}, change of area ΔA is 2.2 m^{2} & change of temperature ΔT is 85 kelvin.
Solution
The given data
Area A = 2 m^{2}
change of area ΔA = 2.2 m^{2}
change of temperature ΔT = 85 kelvin
Step by step calculation
Formula to find α_{A} = 1/A (ΔA/ΔT)
substitute the values in the above formula
= [(1/2) x (2.2/85)]
= 0.01
α_{A} = 0.01
