Superficial i.e area temperature expansion - online calculator.
The amount by which unit area of a material increases when the temperature is raised by one degree is called the coefficient of superficial (i.e. area) expansion. Superficial thermal expansion can be expressed as
dA = A0 γ (t1 - t0) (1)
dA = change in area (m2)
A0 = initial area (m2)
γ = superficial expansion coefficient (m2/m2K)
t0 = initial temperature (oC)
t1 = final temperature (oC)
