Hi there

Can any one tell what is the meaning of boundary conditions for temperature distribution in a flowing viscous fluid in a pipe ?
for example I need some one explane for me this:
T = T1 at r = R, x<0
T = T0 at x = 0, r<R
where T1 is a temperature of well and T0 is a temperature of fluid entering the pipe .

I think you mean: T = T1 at r = R, x>0.

What they're saying is that the tube wall and the fluid temperatures are both T0 for x<0, and that the tube wall temperature suddenly rises discontinuously to T1 at x = 0, and stays at that value for all x > 0.
