Answer to Question #170695 in Physics for chetana

Question

Calculate the surface integral of the function in Ex. 1.7, over the bottom of the box. For consistency, let "upward" be the positive direction. Does the surface integral depend only on the boundary line for this function? What is the total flux over the closed surface of the box (including the bottom)? [Note: For the closed surface the positive direction is "outward," and hence "down," for the bottom face.]

Example 1.7 Calculate the surface integral of v = 2xz x+(x +2) Y+y(z2 - 3) z over five sides (excluding the bottom) of the cubical box (side 2) in Fig. 1.23. Let "upward and outward" be the positive direction, as indicated by the arrows.
