ƞ = ∞ at a point far from it there would be no velocity and the temperature is going to be equal to T1. And if the temperature is going to be equal to T1, then Ф = 0. So with this geometric condition I again write Øy = Øz = 0 and Ф = 0 and at ƞ = - ∞, that means at the point where
आणि ƞ = ∞ त्यापासून काही अंतरावर व्हेलॉसिटी नाही आणि टेम्परेचर T1 च्या समान असेल.
