Expansion
of length
lT
= lo + delta l
l
= alfa x
lo x delta T
Dl = change in
length (m)
alfa = coefficient of thermal expansion (oC-1)
lo = Initial length (m)
delta T = change in temperature (oC)
Expansion
of Area
AT
= Ao + delta A
delta A
= beta x
Ao x delta T
DA = change in Area (m2)
beta = coefficient of thermal expansion (oC-1)
Ao =
Initial Area (m2)
delta T = change in temperature (oC)
Expansion
of Volume
VT
= Vo + DV
delta V
= gamma x
Vo x delta T
delta V= change in
Volume (m3)
gamma = coefficient of thermal expansion (oC-1)
Vo = Initial Volume (m3)
delta T= change in temperature (oC)
