The position vectors of the points P, Q, R, S are i + j + k, 2i+ 5j, 3i + 2j − 3k, and i − 6j − k respectively. The orientation of the resulting normal vector points to the left of the original vector v. Both vectors are considered 2D, projected on the XY plane of the current UCS. nor(v) Determines the 2D unit normal vector to vector v. Hence the points a, b and c are collinear points. This normal vector is the Z coordinate of the object coordinate system (OCS) of the selected object. , (v) determine the influx or outflux, Jw as appropriate and (vi) determine the flow rate, Q, through the tube. Then (ii) determine the vector equation for the velocity, (iii) determine the vector equation for n, (iv) evaluate u. In order to prove a, b and c are collinear, we have to find the sum of coefficient of a, b and c and prove it equal to 0. For each scenario below, (i) draw the unit normal vector, n, to the inlet or outlet on the 2D view.

Three distinct points A, B and C with position vectors a vector, b vector and c vector are collinear if and only if there exist real numbers x, y, z, none of them is zero, such that x + y + z = 0 and xa vector + yb v ector + zc v ector = 0. The position vectors a vector, b vector, c vector of three points satisfy the relation 2a vector - 7b vector + 5c vector.
