Here also see if you only consider this half of the of the plane wall in which he had is being generated, we saw that at this point, at x = 0, . So if you place these two one after the other you would see that there is no difference between this half of the plane wall and A, where some heat is generated, the boundary condition at x = 0, is , the boundary condition at this point is since you have an insulated wall.
येथे हे सुद्धा पहा की जर तुम्ही फक्त अर्धी सपाट भिंत आणि A विचारात घेतले, जिथे काही उष्णता निर्माण होत आहे, तर x=0 ला बाऊंडरी कंडीशन आहे, या बिंदुला बाऊंडरी कंडीशन असल्यामुळे तुमच्याकडे इन्सुलेटेड भिंत आहे.
