Let \boldsymbol{F} = \langle y, -x, x^{2} + y^{2} \rangle and let S be the portion of the paraboloid z = x^{2} + y^{2} where x^{2} + y^{2} \leq 6. Calculate \boldsymbol{F \cdot n} if S is parametrized Do...
1.3. Gas–Liquid Upward and Downward Flows The nature of flow regimes and the liquid fraction distribution gotten from upward and downward flows are expected to be significantly dissimilar, which has been confirmed by the conclusions of [14,15]. They concluded that the liquid fraction is presumed...
