Question

Let y = y (x, t) represent the temperature of an insulated steel pipe of length L.

The temperature of the pipe at time t = 0, is:

y(x,0) = (x/L) * (1- (x/L))  ,  0 ≤ x ≤ L        (1)

and that the temperature at the end points is constant:

y(0,t) = y(L,t)  ,   t > 0                               (2)

The temperature in the steel pipe changes in line with the heat conduction equation:

yt = ayxx  ,  0 < x < L and t > 0                (3)

where a is a constant

 

Use the method of Separation of Variables to determine y = y(x,t) when t > 0.
