Calculate the flux of F across S

[From: ] [author: ] [Date: 11-05-05] [Hit: ]
-∫∫(S) F · dS = ∫∫∫(V) divF dV ,V is the volume of the cube (so x goes from -1 to +1, y from -2 to +2 and z from -2 to +2).divF = 2 x z^3 + 5 x z^3 + 4 x z^3 = 11 x z^3.......
Use the Divergence Theorem to calculate the surface integral ∫∫S F · dS; that is, calculate the flux of F across S.

F(x,y,z) = x2z3 i + 5xyz3 j + xz4 k
S is the surface of the box with vertices (±1,±2,±2)

Thanks in advance!

∫∫(S) F · dS = ∫∫∫(V) divF dV ,

V is the volume of the cube (so x goes from -1 to +1, y from -2 to +2 and z from -2 to +2).

divF = 2 x z^3 + 5 x z^3 + 4 x z^3 = 11 x z^3.

Integrate and you should get 0
