Question

The Trans-Alaskan pipeline is 1,300 km long, reaching from Prudhoe Bay to the port of Valdez, and experiences temperatures from

Answer 1

Answer 2

delta(L) = L*alpha*delta(t)

delta(L) = 1300*108*1.638*10^-10 km

delta(L) = 2.3*10^-5 km = 2.3cm

Answer 3

expansion = 1300*108*0.00000665 = 0.926 km

Answer 4

let's assume it's carbon steel....


the linear coefficient of thermal expansion of carbon steel = 10.8 ^-6 / K

from

?L = Lo x coeff. x ?T = 1300 km x 10.8 ^-6 / K x (73+35)

Answer 5

coefficient of linear expansion
(alpha) = ?L /(L * ?t)
?L = expansion = change in length = alpha*L * ?t
L = 1300*1000 meter
?t = change in temp = 35 - (- 73) = 108 deg C
alpha for steel = 17.3*10^-6 (m/m*C) or (1/K) or (1/C)
-------------------------
?L = expansion = alpha*L * ?t = 17.3*10^-6*(1300*1000)*108
= 2428.92 meter
