Let v be the velocity vector of a steady fluid flow. Is the flow irrotational? Incompressible? Find the streamlines (the paths of the particles). Hint. See the answers to Probs. 9 and 11 for a determination of a path.

Ma128 notes 2.3 addition and subtraction of whole numbers Two models Set model Number line (measurement ) model Set model A + B= N(a intersection b) Let a and b be any two whole numbers if a and b are disjoint sets a=n (a) and b =N(b) N= number of elements in (set A) On the number line whole numbers are geometrically interpreted as distance. Properties of whole numbers Property...
