Seawater has density Ļ = 1025 kg/mĀ³ and flows in a velocity field v = yi + xj, where x, y, and z are measured in meters and the components of v are in meters per second. Find the rate of flow outward through the hemisphere xĀ² + yĀ² + zĀ² = 9, z ā„ 0. That is to say, calculate the surface integral of Ļv. (Let F = Ļv and calculate the flux of F across the surface)
