1. The problem statement, all variables and given/known data Determine the speed of a fluid particle at the origin and at a point (1,-2,0) for each of the following velocity fields when t = 2s. All distances are in meters and t is in seconds. V = (x+2)i + xtj - zk m/s 2. Relevant equations V x dr = 0 dV/dt = u(dV/dx) + v(dV/dy) + w(dV/dz) + dV/dt 3. The attempt at a solution Started with trying to: dx/dt = x+2 ==> dx/(x+2) = dt dy/dt = xt ==> dy/x = tdt This is as far as I have gotten, my textbook doesn't give a single example when dealing with 3-dimensional vector fields and my professor doesn't give any clarification on this program in his notes nor has he given any examples based on 3-dimensional problems or a vector field problem in general.
