When the velocity at a point becomes zero, it refers to ___________(a)

1.	When the velocity at a point becomes zero, it refers to ___________(a) slip condition(b) no slip condition(c) positive slip condition(d) negative slip conditionThis question was addressed to me in an interview for job.This question is from Doublet Flow in section Inviscid & Incompressible Flow of Aerodynamics
Answer» Right CHOICE is (b) no slip CONDITION The explanation is: At the boundary of solids, the velocity at a POINT becomes zero. Dirichlet’s condition is an example of no slip-condition. When the adhesive forces are stronger than cohesive force the particle does not move and HENCE no slip-condition OCCURS.
