So I have this problem, taken from Kraus's heat transfer book.(adsbygoogle = window.adsbygoogle || []).push({});

So deriving the computational molecule, the conditions for (3.251a), (3.251b) is a bit of a no brainer. The issue I am having is about the boundaries for (3.251c) and (3.251d). This is actually the first time I have seen this kind of boundary condition.

How do I deal with this? My hypothesis is to integrate the equations (lol) but the constants of integration stay around... I have no idea what to do at all.andBiare constants. Thanks!γ
