Question

When Reynold’s number limits to infinity, inviscid flow is approached.

(a) True

(b) False

The question was asked in a job interview.

Enquiry is from Continuity Equation topic in portion Aerodynamics – Fundamental Principles and Equations of Aerodynamics

Answer 1

Right choice is (a) True

The best I can explain: For inviscid flows, the influence of friction, thermal conduction, diffusion is limited to a very thin region adjacent to the body surface called the boundary layer and remainder of the flow outside this thin region is essentially inviscid.
