A very long cylinder has temperature T1 impressed on half of its peripheral surface and
temperature T2 impressed on the other half. Find T(r, θ).
governing eq 1/r ∂/∂r(r∂/∂r)+∂2T/∂z2
The Attempt at a Solution
I am right at r=0 ;T=T1 at r=r' T=T2
to make BC homog define new term Q=T-T1
I am confused while define BCs
