1.	The origin is called as _________(a) singular point(b) multiple point(c) sink point(d) source pointThis question was addressed to me in a job interview.Asked question is from Source Flow topic in chapter Inviscid & Incompressible Flow of Aerodynamics
Answer» The correct option is (a) SINGULAR point To explain: For a source flow, DIVERGENCE of velocity is ZERO everywhere expect at the origin where it is infinite. Thus, the origin is a singular point and we can INTERPRET this singular point as a discrete source or sink of a given strength, with a corresponding induced flow field about the point.
