The Trans-Alaskan pipeline is 1300 km long, reaching from Prudhoe Bay to the port of Valdez, and is subject to temperatures ranging from -72°C to +38°C.
(a) How much does the steel pipeline expand due to the difference in temperature? (The coefficient of linear expansion of steel is 1.10 10-5°C−1.)
(b) How can one compensate for this expansion?
