Question

Q3. (2 marks) At time = 0, a particle at point A travelling in a fluid would follow the path AB in the diagram below, but halfway between point A and B in its journey, the flow changes and the particle is directed to point Cinstead. a) The path that the particle actually travelled between A and C is called what (according to the textbook notes that you were referred to in class)? Pathline b) At time = 0, the path AB is called what? (i.e. this type of line is defined at a single instant, and not over time) Streamline O--ET
