Let t be the triangular region with vertices (7, 0, 0), (0, 7, 0), and (0, 0, 7) oriented with an upward-pointing normal vector. assume distances are in meters. a fluid flows with constant velocity field v = 2k meters per second or m/s. calculate the flow rate through t.
calculate the flow rate through the projection of t onto the xy-plane [the triangle with vertices (5, 0, 0), (0, 5, 0), and (0, 0, 0)].
